Title:
OPTICAL METHOD FOR QUANTUM COMPUTING
Document Type and Number:
WIPO Patent Application WO1999056392
Kind Code:
A8
Abstract:
An optical method for quantum computing that makes use of nonlocal effects to construct the quantum gates themselves. A nonlocal interaction in which pairs of atoms interchange two photons produces a large nonlinear phase shift. These nonlinear phase shifts are used to construct quantum logic gates, such as a Controlled-NOT.
