Quantum information: An integrated light circuit
Paul G. Kwiat1
Abstract
There's a long wish list for a workable quantum computer: a viable system must be fast, compact and stable. The first integrated optical quantum logic circuits are a step in the right direction.
Systems that use photons are one of several candidates for making a working quantum computer. One challenge (there are many) is to move beyond the current bulky experiments that involve just a few photons to the kind of stable, miniaturized circuits with very many logic gates that lie at the heart of conventional, classical computers.
