Researchers Develop New Quantum Algorithm

12-19-19

Austin Minnich, Professor of Mechanical Engineering and Applied Physics, Fernando Brandão, Bren Professor of Theoretical Physics, and Garnet Chan, Bren Professor of Chemistry, have developed an algorithm for quantum computers that will help them find use in simulations in the physical sciences. The new algorithm allows a user to find the lowest energy of a given molecule or material. Many people are interested in how to simulate the ground states of molecules and materials. "If we want to do a simulation of water, we could look at how water behaves after it has been blasted into a plasma—an electrically charged gas—but that's not the state water is usually found in; it is not the ground state of water. Ground states are of special interest in understanding the world under ordinary conditions," says Chan. [Caltech story]

Erika Ye Wins 2018 Google PhD Fellowship

04-19-18

Graduate student Erika Ye co-advised by Professors Austin Minnich, Garnet Chan, and Fernando Brandao, has been awarded a 2018 Google PhD Fellowship. The fellowship recognizes and supports outstanding graduate students doing exceptional research in computer science and related disciplines. Erika is attempting to discover what current quantum computers can do that classical computers cannot. Currently she is focusing on computational chemistry—particularly, calculating the behavior of electrons in complex molecules, which ultimately could provide detailed information about reaction rates or how enzymes in cells work.

Fernando Brandao, Bren Professor of Theoretical Physics, and colleagues are developing quantum algorithms for optimization problems. "We are still far from knowing all the applications of quantum computing, and that's part of the excitement—there are possibilities we haven't even dreamed of yet,” says Professor Brandao.
