Better Computing with Photons

摘要

For decades, researchers have been fascinated by the ways in which light acts as a quantum particle (photon). For almost as long, they have also pursued schemes in which photons can be used as information carriers and processors. As they have done every 6 years since the 1960s, the quantum optics community gathered to hear the latest results at the CQO (Coherence and Quantum Optics) and ICQI (International Conference on Quantum Information) conferences held 11 to 15 June 2007 at the University of Rochester in Rochester, New York, USA (1,2). This year's meeting did not disappoint, with a number of exciting devel- opments combining quantum optics with quantum information.
