  • We propose a scheme to achieve a uniform cross-phase modulation (XPM) for two nonclassical light pulses and study its application for quantum nondemolition measurements of the photon number in a pulse and for controlled phase gates in quantum information. We analyze the scheme by quantizing a common phenomenological model for classical XPM. Our analysis first treats the ideal case of equal XPM and pure unitary dynamics. This establishes the groundwork for more-complicated studies of nonunitary… CONTINUE READING
