PHASE-STATE REPRESENTATION IN QUANTUM OPTICS

A phase space for the single-mode light field is constructed by using optical phase variables. This phase-space formalism is directly connec ted to optical-phase-related operators. The phase-state basis \theta] is used to represent various quantum operators and states. Properties of the density operator rho phase-state matrix elements P(theta, theta ') = [theta\rho\theta'] and their relations to phase-related quasiprob ability distributions are discussed. By using the phase representation , different types of number-phase intelligent states are analyzed.
