Nanoscience bridges the macroscopic world and the atomic/ molecular world and provides the ultimate control of materials’ electrical and mechanical properties. By using this recently developed tool, novel devices and systems can be rationally designed to realize functions imagined before only in science fiction. We are particularly interested in the mechanical effect of chemical reactions which can be used as Nanorobotics and Active Matter
Self-propulsion NanomotorElectrochemical reactions in solution generate chemical products on the electrode’s surface and create an ionic flow between cathode and anode. At a microscopic scale, the mechanical force generated by this ionic flow is not negligible and can be used to propel nano/microparticles or pump solution around the electrode. This phenomenon has attracted much interest because of its potential applications in developing novel components in microrobots and in MEMS systems. However, in order to achieve high current density for large driven force, most nanomotors utilize a highly thermodynamically and kinetically favorable reaction such as hydrogen peroxide decomposition and/or hydrazine oxidation as its energy source. These harsh chemical conditions greatly limit the nanomotor’s applications. We are developing highly controllable nanomotor which can operate in the biocompatible electrolyte, which could have potential application in microsurgery and directed drug delivery.
Group Intelligent materials. On the other hand, it is not economically feasible to construct highly complicated nanorobot for complex tasks such as identifying tumors and release drugs at the target. Instead, a rather simple nanorobot with simple structures can be constructed, while the highly complex functions may be encoded into the interactions between many individual nanorobots. Just like the millions of ants forms colony, the group intelligent may emerge from the interaction networks of simple agents. We expect to construct the intelligent networks of nanorobots for highly intelligent nanorobot swarms.
Systematic Material and Active Fluid. As a material system far from thermodynamic equilibrium, the active fluid can be formed with millions of small active particles constantly powered by external sources such as light, chemicals, or heat. This active fluid can be regarded as a new kind of material, which has never been considered until the very recent development of complex science and nanotechnology, enabling the prediction, design, and preparation of active fluid. Nature has made such an extraordinary example of active material system with billions of years of evolution: Life. The question is Can We make Something extraordinary as well? What properties can be discovered in such systems?

Our security expertise is deep and extensive
TrailerSecure is the initiative of experts in the security field with years of experience in both the military and civilian field.
Our know-how includes project development, risk assessment, technology implementation, training and system support.
The idea for the development of a dedicated trailer security system followed over 20 years of accumulated studies in the freight logistics field. These studies pointed to the fact that the matter of trailer protection was long overlooked.
Consequently, our team began working closely with Israeli experts in the fields of mobile video capture, recording and transmission. We also conducted extensive field tests in Europe with prototype systems.
The result was the integration of technologies that enable secure, real-time adaptive data transmission over multiple IP links. They allow for on-the-move connectivity anytime and anywhere, for high bandwidth needs.

In certain regions, hive theft is a sword of Damocles for beekeepers. There aren’t many ways to prevent it, and it can be difficult to recover stolen colonies or obtain redress. Faced with this observation, the French startup Hostabee has developed a discreet GPS device that is easy to place inside the hive: B-swarm.
B-swarm enables you to locate your hive in real-time, alerts you in the event of unusual movement, and makes it possible to monitor its movements on a map if it is stolen. Easy to use, it is equipped with a CR 123 Lithium battery with a battery life of around 12 months.
The advantages of B-swarm:
– Real-time, 24/7 hive geolocation (precision: +/- 20 meters)
– Possibility of receiving SMS alerts if your hives move
– 12-month battery life (replaceable battery) with the battery level displayed in the app.
– Low-frequency radio waves to avoid disturbing your bees
– Technology used: Sigfox* – Dimensions: 8.5 x 5 x 2.5 cm (3.35 x 1.97 x .98 in), for a discreet device
– Simple! Does not require an additional device to transmit data. It is sent directly from the B-swarm to the app.
– Web application accessible from any device (smartphone, computer, tablet – all makes) via your web browser.
– Functions with a yearly subscription system (see “Use” tab for more information” .
*A LoRa WAN version also exists, equipped with a rechargeable lithium ion battery, with around 6 months of battery life.


Electric Vehicle Charging Equipment (EVCE)
With the increase in the number of electric and hybrid vehicles has come a proportionate increase in the number of charging points available on sites, especially shopping centres and retail parks. Charging points present a number of hazards as they are designed to be used by the public whilst presenting a minimal risk of fire or electrocution.
Provision of Electric Vehicle Charging Equipment is covered by the Provision and Use of Work Equipment Regulations 1998 and the Electricity at Work Regulation 1989 – due to the risk of electrocution. Both the Electricity at Work Regs and the IEE Regulations BS 7671 indicate that the charge points need to be checked, maintained and tested on a regular basis to ensure that all reasonably practical precautions have been taken to ensure the health and safety of users.
New installations should be in accordance with the IET Code of Practice for Electric Vehicle Charging Equipment Installation (4th Edition). The updated edition is particularly important as it aligns with the BS 7671:2018 Requirements for Electrical Installations (IET Wiring Regulations, 18th Edition). Clients should be aware of unauthorised charging/use of extension leads which can be a cause of vehicle fires (not the charge point). Therefore, the charging points should be suitably located where the potential secondary damage caused by fire is low.
Types of Electric Vehicle Charging Points
There are three main types of Electric Vehicle (EV) charging point, each defined by power output and hence how quickly they can charge an electric vehicle. While vehicle connector types can be conceived as a problem, most electric vehicles are supplied with multiple cables allowing connection with a wide range of EV charging points:
Slow Charge (up to 3kW)
Slow charging an EV utilises a standard BS1363 13A socket outlet found in any UK household or business premises. These charging points use approximately 3kW of power and can fully charge an EV in around 6-8 hours.
- Almost every EV can be charged using a slow charger.
- Low cost of installation.
- Charging overnight utilises low electricity tariffs.
- Cuts CO2 emissions.
Fast Charge (7-22kW)
With a charge current of around 32A (7kW), using a fast charger reduces charging time to around 2-4 hours. These types of charger are commonly found at charging points found on public streets and those within service stations. Although not all electric vehicles are capable of being charged at 32 amps, most models can be connected to them using the correct connector and will automatically draw either 13 or 32 amps depending on their charge capability.
- Widely available.
- Quick charge time.
Rapid Charge (up to 50kW)
Rapid chargers supply AC or DC current from a dedicated charge point using a tethered, non-removable cable, similar to a traditional fuel pump. Rated at around 50kW, charging an EV to 80% capacity typically takes under 30 minutes. Similar to fast charging, not all electric vehicles can use a rapid charger, but will draw a current dependent on their individual charge capability. Although extremely convenient being able to charge in such a short period of time, repeated rapid charging can have an adverse effect on battery life.
- Extremely quick charge time.

Why Choose FoIP?
FoIP Technical Overview
Unlike a traditional fax server implementation, in which it is connected to the phone network (PSTN) through a local PBX, FoIP works via a T.38 protocol that describes how to send a fax over a computer data network. T.38 requires a T.38 capable VoIP gateway as well as a T.38-capable fax device.
A fax server that sends or receives faxes using T.38 looks just like any other non-FoIP fax device to its partner. The two end points establish a session, send and verify the transmission of one or more pages and then complete the session with active confirmations from both sides. The difference with a FoIP enabled server is that the first part of the communication session from the server to the network traverses an IP network rather than traveling directly over the PSTN. If the partner device is directly addressable on the same network, the session can use T.38 for the entire transmission. But if the devices are separated by the telephone line, the IP switch manages the “unwrapping” of T.38 packets into standard T.30 fax transmissions over the PSTN.
What is CloudFax FoIP?
Cloud Fax over Internet Protocol (FoIP), also known as IP Faxing, is a method of sending faxes over the Internet and changes the transmission medium of faxing in much the same way that Voice over IP (VoIP) changes the transmission medium of a phone call.
With FoIP, fax information is sent as “IP Packets” over the Internet rather than as an analogue signal via a phone line and provides an even wider range of benefits than VoIP.
By moving to a Fax over IP environment, and routing faxes over their IP network, organizations can slash the telecommunications cost of every fax, improve the efficiency of their staff, eliminate the ongoing cost of fax consumables and maintenance and increase the overall security of their fax processes.
Cloud Fax. It's what we do.
CloudFax Fax over IP (FoIP) enables you to virtualize your fax infrastructure with our T.38 Fax over IP (FoIP), by sending and receiving faxes via a Voice over IP (VoIP) network – such as those from Cisco, Avaya, Alcatel-Lucent, Quintum, and others.
With over 70% of new fax ports/lines purchased today being IP-based, it is clear that the demand for Cloud Fax over IP (FoIP) solutions has never been greater. More organizations have come to realize the cost savings and productivity benefits that derive from deploying a FoIP server. In fact, even if you don't have a VoIP network in place today, you can still implement FoIP and virtualize your fax servers through use of our SR140 fax software and media gateway. With the Cloud FoIP T.38 solution, you can:

Many people are unaware that the drone represents significant progress in how a number of old and new technologies are now being used.
The fact is that drones quickly change the face of war. Instead of risking the lives of soldiers, the Military is now sending drone aircraft to handle dangerous work.
Beyond the concept of using drone aircraft for communication, there are a number of other useful drone applications. You can navigate to https://www.mirragin.com.au/ to know more about drone aircraft and its various uses.
Measurement – There is no better way to map environmental problems than using drones. For example during the Gulf oil spill dozens of planes were sent every day to track the spill. If a drone is available and equipped with the right camera and sensor, the cost of tracking a spill can reduce costs by a factor of 100. Also by centralizing the way data is collected, the task of data analysis will be much easier and certainly more appropriate.
Incidental Weather Conditions – Several years ago an ice storm had a devastating effect on thousands of square miles around the State of Kentucky. The problem includes power cuts, telephone outages and people who are completely stranded by ice and cold. Here ACPT will provide communication while this ice bound area allows people a reliable means of communication.
These are just a few ideas when using drones to help humanity. There are many, more ways drones can be used to gather information efficiently and hopefully, in the future, humanity will use drones to help mankind than to use drones for tighter warfare.

|Richard Manning Karp
(born 1935) is a computer scientist and computational theorist,
notable for research in the theory of algorithms, for which he
received a Turing Award in 1985 and the Kyoto Prize in 2008.
Born to Abraham and Rose Karp in Boston, Massachusetts, Karp has three
younger siblings: Robert, David, and Carolyn. He attended Harvard
University, where he received his Bachelor's degree in 1955, his
Master's degree in 1956, and his Ph.D. in applied mathematics in 1959.
He then worked at IBM's Thomas J. Watson Research Center. In 1968, he
became Professor of Computer Science, Mathematics, and Operations
Research at the University of California, Berkeley. Apart from a
4-year period as a professor at the University of Washington, he has
remained at Berkeley. Richard Karp was awarded the National Medal of
Science, and was the recipient of the Harvey Prize of the Technion and
the 2004 Benjamin Franklin Medal in Computer and Cognitive Science for
his insights into computational complexity. In 1994 he was inducted as
a Fellow of the Association for Computing Machinery. He is the
recipient of several honorary degrees.
His citation for the Turing Award was as follows:
For his continuing contributions to the theory of algorithms including
the development of efficient algorithms for network flow and other
combinatorial optimization problems, the identification of
polynomial-time computability with the intuitive notion of algorithmic
efficiency, and, most notably, contributions to the theory of
NP-completeness. Karp introduced the now standard methodology for
proving problems to be NP-complete which has led to the identification
of many theoretical and practical problems as being computationally
In 1971 he co-developed with Jack Edmonds the Edmonds-Karp algorithm
for solving the max-flow problem on networks, and in 1972 he published
a landmark paper in complexity theory, "Reducibility Among
Combinatorial Problems", in which he proved 21 Problems to be
NP-complete. In 1987 he co-developed with Michael O. Rabin the
Rabin-Karp string search algorithm. In 1980, along with Richard J.
Lipton, Karp proved the Karp-Lipton theorem (which proves that, if SAT
can be solved by Boolean circuits with a polynomial number of logic
gates, then the polynomial hierarchy collapses to its second level).
He has made many other important discoveries in computer science and
operations research in the area of combinatorial algorithms. His major
current research interests include bioinformatics.

Question: I keep getting an error message, "Fail to create reference rasterizer 3D Device. -D3DERR_NOAVAILABLE", when I try to open 3D view. What should I do?
Answer: GC Image uses OpenGL for its 3D graphics rendering. To solve the problem, you need to install the latest driver for your graphics card.
This problem mostly likely occurs if you have a graphics card with Intel chipset. As stated by Intel, "Graphics drivers that come with Microsoft Windows or that are downloaded from Windows Update typically do not support OpenGL." Please see here for details:
and download the driver as follows:
-> Go to http://downloadcenter.intel.com/Default.aspx?lang=eng
-> Select Graphics > Desktop > Graphics Controllers > Select your chipset
-> Download driver based on your version of Windows
-> Install new driver
Then the software can visualize the data in 3D view.

Thin walled profiles and composite beams
CSection & CBeam
To help section and beam design
Using composite beams is a real trend today in many engineering applications. However, the mechanical behavior of such composite structures is not so easy to understand, to predict and to compute. Composite beam design is truly difficult, especially when working with strongly anisotropic materials and/or thin-walled open/closed profiles.
The “CSection & CBeam” package provides an efficient numerical tool devoted to the simulation of the mechanical behavior of homogeneous or composite beams. Easy to use by engineers and technicians, it can really help to design and optimize thin walled profiles or composite beams.


Your vehicle may not even have a key — it may have a “flip key” or “smart key” with a small blade. The technology used to enter and start these cars relies on a computer chip being present in the remote and the vehicle. These two chips must talk to each other in a way that will unlock or start the vehicle. The concept here is the same as transponder keys. If you don’t have a spare, it’s much less costly to get a duplicate made than to have to reprogram the car to a new one.


Apple has announced it will be going the home AI unit arms race against Google and Amazon with the launch of its HomePod later in the year.
According to Tim Cook, Apple CEO, the focus will be on music in the first instance: “Just like we did with portable music we want to reinvent home music.” The HomePod will launch in the US, UK and Australia in December. It will be priced at a (surprisingly expensive) $349 and come in white and space grey. Combined with Siri you’ll be able to ask it to “play more from this band” or ask for more songs with the same guitarist and the like.
You will also be able to use it to set a timers and give you reminders. You will be able to send a text with apple Messages, control the household lights and hook up with other connected devices through HomeKit. And needless to say it will also read the news and weather to you.
The competition is hotting up in the home AI unit space and many Apple fans will be interested and excited to have access to a new device to add to the suite of gadgets they offer. That’s probably how they will justify the higher price tag. But with an end of year launch date, Apple has some catching up to do.

CB radio installation for many people seems like a daunting task that can only be handled by a professional. This is largely due to the fact that, besides installing the radio onto your vehicle, there’s also tuning to be carried out. Through this short but detailed guide, I’ll take you the steps you should take to set up a CB radio on your vehicle like a pro.
How to install CB radio in the car
All CB radios function the same and within the 40 channels between 26.965MHz and 27.405MHz. Despite this, installing your CB radio needs to take into account a number of factors including size and design. Where you mount the portable CB radio should take into account factors such as:
- How accessible the radio is when mounted
- How safe the radio is from heat, dust, moisture and theft
- How easy it is to view the channel you’re using
- Whether the radio obstructs efficient use of your vehicle
Taking these into account, here are some of the best places to mount a CB radio:
Many CB radio owners prefer to mount their units on the dashboard. Here, you’ll get a clear view of the radio and easily access it. It also offers minimal obstruction to the vehicle’s users. The downside of mounting your CB on the dashboard is that it’s directly exposed to the sun’s heat and is prone to theft.
Above rear view mirror
If your vehicle has ample head space, I’d recommend you mount your CB above the rear view mirror. At this point, the CB is easily accessible, isn’t exposed to the sun’s heat and doesn’t cause any obstructions. You should however ensure that the CB device is safely secured to prevent it from falling off.
The dashboard’s center console
This location offers the most mounting options. If you have a small CB, its easy to install within one of the compartments built into the dashboards center console. Other great installation points include the side of the center console and under the dashboard.
Once the CB is mounted, you’ll need to install the antenna. I’d recommend mounting it on the vehicle’s roof as this will provide the best signal reception. Once this is installed, you’ll have to connect the antenna to the CB using a coaxial cable. Next, connect the CB to the power source which is most likely the cigarette lighter socket or directly to the car’s battery.
How to tune a CB radio
Like many CB radio owners, I have found that tuning the unit will require patience. The following are the steps to take when tuning a CB Radio:
- Connect the coaxial cable to the SWR meter via the antenna port. Next, connect the SWR meter to the CB using the jumper lead via the transmitter port.
- Switch on the SWR to FWD’ and turn on the radio to channel 1.
- Press the mic button and hold while turning the SWR adjusting knob until the needle moves to the extreme end of the range.
- Switch the SWR to SWR’ while still pressing the microphone button.
- Read and record the SWR reading and repeat the procedure for the remaining 39 channels.
Your goal is to achieve an SWR ratio of between 1.5:1 and 1:1 for all channels. Anything above 1.5:1 will shorten your CB radio’s life. You should note that if the SWR reading on channel 40 is higher than that on channel 1, you will have to shorten the length of the antenna and vice versa.
As you can see, installing and tuning you CB radio isn’t as hard as it seems. If you follow the steps outlined in this guide, you should be able to mount and tune your CB in a few hours.


For a small body with mass m in an elliptic orbit about a much larger body with mass M, the total energy is
where r is the distance between the centers of the bodies and a is the semimajor-axis of the elliptic orbit.
Solving this equation for the velocity gives
where μ = GM.
The speed in a circular orbit with radius r, where a = r, becomes
The drawing above shows that the semi-major axis is
The necessary speed increase in the low circular orbit is the difference between the speed in the elliptic Hohmann orbit at r = r1 and the speed in the lower circular orbit:
In a similar way we find the speed increase at r2 to achieve a circular orbit there:
The time of transit in the Hohmann orbit is one half the period of the full elliptic orbit. Kepler's third law gives:
The following section is only relevant for the simulation "Hohmann transfer orbit to Mars".
We now consider a Hohmann orbit where the spacecraft has to meet another body when it arrives at the outer orbit.
In the illustration below the outer body is Mars and the spacecraft leaves just outside the Earth.
The spacecraft has to leave the inner orbit when the angular displacement between the spacecraft and Mars has a certain value α, in this case 44o.
The period of Mars is
Then its angular velocity is
In the time tH Mars moves an angle ω2tH .
The spacecraft moves a larger angle π in the same time. So the angle between the spacecraft and Mars at the launch into the Hohmann orbit should be (in radians)
where Mars is ahead of the spacecraft.
In the simulation the angle between the spacecraft and Mars is zero. The angle at time t is
When does this angle become equal to the value in equation 2?
Simply setting the expression in (3) equal to α (from equation 2) will give the time when the spacecraft is the angle α ahead of Mars.
We have to wait until the angle between the two bodies is 2π - α to launch the spacecraft into the Hohmann orbit. Therefore the time of launch is


Making a part of home decor and getting help to create a cozy effect into the interior, Himalayan salt lamps are a good option but in offices do they serve? And if YES, then what’s their incorporating aspects with a professional working environment? Let’s discuss why to have a Himalayan salt lamp on your office table to avoid electromagnetic radiation?
What is Electromagnetic Radiation?
Scientifically, EM or EMR electromagnetic radiation is the discharge of electromagnetic radiant energy. This EMR includes gamma rays, ultraviolet rays, visible light, radio, and microwaves. The effect of electromagnetic radiation on living organisms depends upon the usage and frequency of the waves.
How can Himalayan Salt Lamp Fight Against Electromagnetic Radiation?
There are lots of Health Benefits of Himalayan Salt, as we’ve explored the scientific and environmental reality of negative ions present in Himalayan rock salt, these ions are in actual the molecules which makes a value of the salt. Although, just a simple piece of Himalayan rock salt is itself can pass positive waves, especially the hygroscopic process ensures its more benefits.
This hygroscopic process occurs when the heat evaporates the salt particles into the air and dilutes negative ions by this mean. And coming back to our concern, these negative ions are those preventers which combat against the electromagnetic radiation. The waves of negative ions are actually negative for such hazardous rays. Electromagnetic radiation is in electronic devices involve frequency of rays which are considered not really sever, therefore non-healthy usage on daily basis is itself insecurity for sustainable health.
Then why not try something which is natural and recommended to experience benefits gradually but really. We have a wide range of Himalayan salt lamps made by ensuring both environmental and interior needs for a healthy lifestyle.

There is one cool new feature, which was actually really simple to implement. VeskuMaps now uses magnetometer to detect the orientation of the device and shows it on the map. First I was thinking of adding traditional compass to the bottom corner of map view, but then I realized that most of the time people are actually not that interested where the north is, instead they want to understand that which way they are facing. This they should be able to see now quite easily. In the map view north is still always up, and in the bottom left corner there is miniature N9 rotated to show what orientation the device is pointing.
Another new feature is that now it is possible to get back to map view from details-page of a location by clicking the minimap in the details-page. Main map is centered to the selected location and the map marker is opened.
In addition I added loading indicator to show when the app loads initial map and an error message to show when connecting to Google's server failed.

A telescope is an optical instrument that makes distant objects appear magnified by using an arrangement of lenses or curved mirrors and lenses, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. The first known practical telescopes were refracting telescopes invented in the Netherlands at the beginning of the 17th century, by using glass lenses. They were used for both terrestrial applications and astronomy.
The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. The word telescope now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors.


I have received my PhD from University of South Carolina (USC) in Computer Science. I was working in Autonomous Field Robotics Laboratory (AFRL) under supervision of Dr. Ioannis Rekleitis. My research is on area coverage both for two and three dimensional areas, with particular applications in aquatic domain. I want to enable more efficient and task oriented coverage techniques for environmental monitoring and survey operations. I sometimes draw inspiration from human expertise in performing specific tasks and try to adapt similar reasoning in algorithms I am developing for surface and underwater robots.

What is Quantum Computing : Quantum computing is computing using quantum-mechanical phenomena, such as superposition and entanglement. A quantum computer is a device that performs quantum computing.
They are different from binary digital electronic computers based on transistors. Whereas common digital computing requires that the data be encoded into binary digits (bits),
each of which is always in one of two definite states (0 or 1), quantum computation uses quantum bits, which can be in superpositions of states.
A quantum Turing machine is a theoretical model of such a computer, and is also known as the universal quantum computer. The field of quantum computing was initiated by the work of Paul Benioff (de) and Yuri Manin in 1980, Richard Feynman in 1982, and David Deutsch in 1985. A quantum computer with spins as quantum bits was also formulated for use as a quantum spacetime in 1968. What is Quantum Computer of work in Bitcoin.
Quantum Computer Work in Bitcoin
Bitcoin is a digital currency and payment system based on classical cryptographic
technologies which works without a central administrator such as in traditional currencies. It
has long been questioned what the impact of quantum computing would be on Bitcoin, and
cryptocurrencies in general. Here, we analyse three primary directions that quantum
computers might have an impact in: mining, security, and forks. We find that in the nearterm
the impact of quantum computers appear to be rather small for all three directions. The
impact of quantum computers would require considerably larger number of qubits and
breakthroughs in quantum algorithms to reverse existing hash functions.
Mining Bitcoin would not be any better on a Quantum Computer. SHA-256, the algorithm used to mine Bitcoin, is a one way function. That means that you can pre-compute all the possibilities without running it, which what gives a quantum computer it’s power.
There are two main flavors of encryption at play in Bitcoin: What is Quantum Computer of work in Bitcoin
1) Hashes – Bitcoin uses SHA-256 and RIPEMD as hashing algorithms. This generates new blocks, hides an address from the public key, and allows some checksums.
2) ECC – This is the public/private key pair that lets you sign and prove you own your Bitcoin.
About Quantum Security
ECC is vulnerable to a quantum attack, but you’d need the public key. Since the public key is protected by the hashing algorithms, which are thought to be quantum resistant, simply using change addresses and always emptying all inputs in a transaction sufficiently protects your coins.
You are only at risk if you don’t use this default behavior, which has been part of wallets for years now.
What is Quantum Computer of work in Bitcoin
Mining System & Algirothms
One of the technologies that Bitcoin is based on is the SHA-256, a cryptographic hashing
function which turns arbitrary input data into a 256 bit string (the “hash”). This is a one-way
function, so that it is easy to find the hash from an input but not the other way around.
Bitcoin mining consists of the search problem of finding an input (the “nonce”) combined
with information of the most recent block that generates a hash that is less than a target value
T, the maximum number that is acceptable to be considered a valid Bitcoin hash. The target “What is Quantum Computer of work in Bitcoin”
value is continually being readjusted such that the average time between blocks is 10 minutes
(at the time of writing the target is approximately T = 8.9x 1011
, much smaller than If it were possible to find a quantum algorithm to invert SHA-256
efficiently, then we could indeed mine Bitcoin easily. However, the value of Bitcoin comes
from the difficulty of finding such solutions, which gives it “proof of work”. Currently it is
believed that there is no efficient algorithm, classical or quantum, which can invert SHA-256.
Hence the only way is a brute force search, which classically means trying different inputs
until a satisfactory solution is found.
Quantum mechanically, we have Grover search, which seems to be a perfect solution to this
kind of problem, and has a quadratic quantum speedup. Let us see how well this strategy
works when comparing it to mining with a classical computer. Classically, the success
probability of mining a block with guesses is given by , where”r” is the hash rate (the
number of guesses made per second), and “t” is the time in seconds. For a quantum miner running Grover’s algorithm the success probability is
“rq” is the
number of Grover iterations per second, which we can call the “quantum hash rate”.
Now there is a different dynamic between the classical and quantum miner because Bitcoin is
designed to find a new block on average every 10 minutes (=600 seconds), and hence the
nature of the search problem changes in this time. In order for the Grover procedure to give a
high success probability, a quantum miner should run their algorithm for a time “t” before the
problem changes, and then make a measurement. Meanwhile, the classical miner has in this
time been trying as many nonces as possible. So the quantum miner is hoping that none of
the classical miners have found a solution yet during the Grover evolution. Since the interval
between blocks follows an exponential distribution, the probability that the block is still
mineable is given by
Assuming a constant cost of running a quantum computer for a
given amount of time, the profitability of quantum Bitcoin mining is then
where R is the reward (currently equal to the price of 12.5 Bitcoins plus transaction fees) andC
is the cost of running the quantum computer.
