Abstract

Previous studies revealed that the "faster-than-c" propagation is perfectly in accord with special relativity. While this argument is correct, it is based on the classical wave theory. On the other hand, this phenomenon can be studied in situations when a pulse consists of only a few photons, or, when the number of photons is large, but the sensitivity of the light detection system is at or better than the shot photon noise level. In both cases, quantum mechanical treatment of both the light and the medium is necessary to provide a clear description of the system's dynamics.
