The world of computer technology that is envisioned by scientists today could be coming up after a decade from now. The experts are trying to put their best feet forward in coming up with the ideas and algorithms that reduce the waiting time for the arrival of quantum processors which will be able to solve the errors and noise.
A team at Virginia Tech Chemistry and Physics including research scientists has advanced Quantum simulation by devising an algorithm that can more effectively calculate the attributes of a molecule being tested in a noisy quantum computer. Insights of the research have been provided by Phys.org which entails the features of the research of having been come from Virginia Tech College of Science faculty members Ed Barnes, Sophia Economou, and Nick Mayhall recently published a paper in Nature Communications detailing the advancement.
The most important use will be simulating the molecular properties which can lead to advancement in material design and drug discoveries in the coming years. The classical style, however, complicates the process, delivering high errors and noisy calculations. Quantum Computers at present carry out different calculations that are far more efficient than the classical computers of the date. They are most akin to the Classical computers excerpts for the fact that they run sequences of logic gates in equations which are termed as “Quantum Gates” and which when put in a sequence forms the basis of the “Quantum Circuits” to the bits of information. The scientists found it difficult to design a circuit that is small as well as accurate.
As reported in the article, The Virginia Tech team addressed this issue by developing a method that grows the circuit in an iterative way.
“We start with a minimal circuit, then grow it as we add on the logic gate after a logic gate in short circuits until the computer finds the solution,”Mayhall
said Mayhall, an assistant professor in the Department of Chemistry. As a description of the second major advantage of the algorithm is that Barnes, Economou, and Mayhall designed it to accommodate itself on the basis of the molecular system being simulated by the design. Different molecules will authenticate their own circuits, uniquely tailored to them. The “interdisciplinary collaboration” between the essential Virginia Tech’s departments of Chemistry and Physics—Barnes, Economou, and Mayhall and a team of graduate students and postdocs from both departments— have been granted funds more than $2.8 million from the National Science Foundation and the U.S. Department of Energy.
