Quantum chemistry is easy (if you have access to a quantum computer)
4:15pm - 5:00pm
The calculation time for the energy of atoms and molecules scales exponentially with system size on a classical computer but polynomially using quantum algorithms. A consequence of this is that even small quantum computers can outperform the most ambitious supercomputers ever conceived for simulating nature at the molecular scale. Results published by D Wave in the September 9th 2005 issue of Science identify 49 quantum bits as the current crossover point for quantum chemistry, when a calculation could be performed which is at present out of reach of the world's largest supercomputers. In this presentation I will review the techniques we use for performing quantum chemistry calculations using quantum computers, and will argue that this new technology will make conventional supercomputing approaches to atomic and molecular simulation obsolete.

D-Wave Systems Inc.
President and CEO of D-Wave Dr. Geordie Rose leads an international effort consisting of more than 50 of the world's leading physicists, computer scientists, and engineers. Together they are working to make the vast power and speed of quantum computers available to industrial and government customers. Dr. Rose holds a Ph.D. in theoretical physics from the University of British Columbia. He is co-inventor on 25 filed patents in the field of superconducting electronics, and has co-authored eight peer-reviewed scientific articles, which have appeared in the scientific journals Physical Review, Journal of Low Temperature Physics and Physica. Dr. Rose was awarded a 2001 Business in Vancouver 40 Under 40 award, and has been profiled in BC Business, the Vancouver Sun, The Province, Vancouver magazine, the Globe and Mail, the National Post, USA Today, MIT Technology Review magazine and Business 2.0. One of his business strategies was featured in a Harvard Business School case study. Since the inception of D-Wave, Dr. Rose has raised over $20M, including a US$7.1M round closed in June 2003 led by US venture capital firm Draper Fisher Jurvetson.
