Abstract

The use of optical quantum-nondemolition devices in quantum information processing was discussed. Several optical interferometers, that signal the presence of a single photon in a particular input state without destroying it, were described. Expanded protocols were constructed to perform quantum-nondemolition detections of single photons that leave the polarization invariant.
