... An all-optical transistor where one ‘gate’ photon controls the propagation of a ‘source’ light beam, is a long-standing goal in optics. By reversibly stopping a light pulse in an atomic ensemble contained inside an optical resonator, we realize a device in which one stored gate photon controls the r ...
