By Geoff Brumfiel of Nature magazine Bill Murray is a man with secrets. Along with a handful of other scientists based at CERN, Europe's particle-physics facility near Geneva, Switzerland, Murray is one of the few researchers with access to the latest data on the Higgs boson -- the most sought-after particle in physics. Looking at his laptop, he traces a thin black line that wiggles across a shaded area at the centre of a graph.

PHYS771 Quantum Computing Since Democritus University of Waterloo, Fall 2006 Tuesdays and Thursdays, 1:00-2:30pm BFG Building, 2nd floor seminar room (BFG2125) Instructor: Scott Aaronson 3141 Davis Centre Email: scott at scottaaronson dot com Office hours: After class or by appointment Description: This course tries to connect quantum computing to the wider intellectual world. We'll start out with various scientific, mathematical, or philosophical problems that predate quantum computing: for example, the measurement problem, P versus NP, the existence of secure cryptography, the Humean problem of induction, or the possibility of closed timelike curves.
