Norman Hascoe Distinguished Physics Lecture

Monday, April 12, 2010
4:00pm – 5:00pm

Storrs Campus
Gant Science Complex P-38

Professor Alan Aspuru-Guzik, from the Dept. of Chemistry & Chemical Biology at Harvard University, will present, “Quantum Computing for Chemistry.” The Schrodinger equation, as currently solved using current classical computers, cannot be solved exactly for most many-body systems, and in particular, atoms, molecules and solids. On the other hand, as originally suggested by Feynman in 1982, quantum systems allow the simulation of other quantum systems in a tractable fashion. With the advent of quantum computing, and important developments such as the 1994 discovery of an efficient factoring algorithm, and in 1997 an efficient quantum simulation algorithm, the realization of Feynman's proposal is getting closer to reality. In 2005, we proposed a quantum algorithm for obtaining exact molecular energies efficiently using quantum computers. In this talk, I explore the developments in my group since then, which include the development of algorithms for molecular properties and chemical dynamics. I also describe the recent quantum computing experimental calculation of the hydrogen molecule in a minimal basis, carried out in collaboration with the group of Andrew White (U. of Queensland). Finally, I will briefly describe the application of quantum computers to finding low-energy conformations of protein models, and give a sneak peek of the recent quantum experiment that shows this carried out in the lab for the first time.Refreshments will follow the talk, in the Gant Complex, Physics Library, Room P-103.
