SUMMARY:Quantum Computing
DESCRIPTION:Featuring Ray Laflamme\, University of Waterloo\, Perimeter Ins
	titute\, Ontario\, Canada\nHosted by: Andrew Cohen\n\nPart of the Physics D
	epartment Colloquia Series.\n\nBenson T. Chertok Memorial Lecture.\n\nAdvan
	ces in computing are revolutionizing our world.  Present day computers adva
	nce at a rapid pace toward the barrier defined by the laws of quantum physi
	cs.  The quantum computation program short-circuits that constraint by expl
	oiting the quantum laws to advantage rather than regarding them as obstacle
	s.  Quantum computer accepts any superposition of its inputs as an input\, 
	and processes the components simultaneously\, performing a sophisticated in
	terference experiment of classical inputs.  This "quantum parallelism" allo
	ws one to explore exponentially many trial solutions with relatively modest
	 means\, and to select the correct one.  This has a particularly dramatic e
	ffect on factoring of large integers\, which is at the core of the present 
	day encryption strategies (public key) used in diplomatic communication\, a
	nd (increasingly) in business.  As demonstrated some  years ago\, quantum c
	omputers could yield the most commonly used encryption protocol obsolete.  
	Since then\, it was also realized that quantum computation can lead to brea
	kthroughs elsewhere\, including simulations of quantum systems\, implementa
	tion of novel encryption strategies (quantum cryptography)\, as well as mor
	e mundane applications such as sorting.  I will describe how a quantum comp
	uter work and will give a demonstration using NMR technology.
