what is quantum computing quantum
computing is a new type of computing
architecture they will make our devices
millions of times faster than they are
today in order to solve a problem
today's computer must run through all
possible solutions and sell finds a
single one that works for example if
you're looking for a name in a phone
book with 7 billion names we'd have to
go through each name one by one until we
found a match
similarly classical computers work using
bits single pieces of information that
exists either a 1 or a 0 quantum bits or
qubits however can exist as both a 0 and
a 1 simultaneously
this means a quantum computer can check
all possible solutions to a problem at
one time for example just 30 qubits can
simulate 2 to the 30 or 1 billion
possibilities in a split second and this
is awesome for solving huge problems
that are virtually an infinite number of
possible answers problems that simply
cannot be solved by today's computers
but this same superpower will also pose
a major threat to cyber security the
encryption algorithms of today rely on
massive math problems that are near
impossible to solve like factory numbers
hundreds of digits long a single quantum
computer whoever could easily decrypt
any piece of sensitive information and
render our entire system of
cybersecurity obsolete
that said quantum computers will likely
also allow us to create new quantum
methods of encryption so I'm not too
worried about that
still that begs the question well the
first quantum computer be used for good
or evil
