| Περίληψη: | Presents a cavity quantum electrodynamics experiment to detect a single photon non-destructively. Use of atomic interferometry to measure the phase shift in an atomic wavefunction, caused by a cycle of photon absorption and emission; Method amounting to a restricted quantum non-demolition measurement which can be applied only to states containing one or zero photons; Lead to quantum logic gates based on cavity quantum electrodynamics, and multi-atom entanglement. |
