hyderabad researchers at the international institute of information technology hyderabad iiith designed a novel way of performing quantum chemistry calculations the new method helps to predict the molecular properties and model chemical reactionsutkarsh azad dual degree research student at iiit h under the guidance of harjinder singh attempted to showcase the abilities of nisq noisy intermediatescale quantum device the current generation of quantum computers that use the properties of quantum physics to perform calculations outperforming traditional machines such as laptops and others for doing quantum chemistry calculationsa student of the center for computational natural sciences and bioinformatics ccnsb iiith utkarsh said that modelling chemical reactions on classical computers requires approximations because they cant exactly calculate quantum behaviour of more than just a couple of electronsthe computations are too large and timeconsuming and each simplification reduces the overall accuracy of the calculations thereby limiting their usefulness whereas quantum computing works differently through phenomena known as entanglement we are able to describe electronelectron interactions without approximations he said and added that quantum computing enables us to model nature as it is without any simplificationsthe research titled quantum chemistry calculations using energy derivatives on quantum computers was recently featured in the nisq computing newsletter by the usra research institute for advanced computer science
