註釋

The preservation of information encoded into the relative phase and amplitudes of optical pulses during storage and retrieval in an optical memory based on stimulated photon echo is demonstrated. Furthermore photon echoes stored in spatially separated optical memories in several temporal modes, are retrieved and then combined at a beam splitter. They show almost perfect interference demonstrating both phase preserving storage and indistinguishability of photon echoes. Finally, we report an interference experiment of spontaneous emission of light from two distant solid-state ensembles of atoms and the resulting high fringe visibility implies that the observed spontaneous emission is coherent.
