Quantum computing, entanglement, and invariant theory
Feynman proved (to his satisfaction) that quantum phenomena cannot be
modeled with a digital (classical) computer. He then set his sights on
developing a "quantum computer" to carry out this modeling. This work lay
in obscurity until Shor showed (assuming the existence of a quantum
computer) that there are polynomial time quantum algorithms for factoring
numbers and solving for discrete logarithms. These results and Grover's
algorithm for unordered search have caused a recent surge in interest in
this field. In this lecture we will give an idea of the mathematical
aspects of quantum, computing (with no of physical implementation),
describe a quantum algorithm and attempt to explain some joint work with
David Meyer on entanglement.
Refreshments will be served in Math Annex Room 1115, 3:15 p.m.
