Abstract :
Summary form only given. The collision of optical pulses in a fiber is a promising concept for quantum-nondemolition (QND) measurements of the photon-number using the Kerr effect induced cross-phase modulation (XPM). Spectral filtering of solitons produced strong photon-number noise reduction below shot noise in direct detection. We present a novel QND experiment based on the XPM-induced frequency shift of colliding pulses and on direct detection using spectral filtering.
