Paper Abstract

The evolution of the optical NOON state is investigated. The environments of the evolution are the thermal noise and amplitude damping due to fiber loss. The characteristic function and the density matrix of the time-dependent state are deduced strictly. We calculate the relative entropy of entanglement for the truncated time-dependent state for N=1 case. The phase measurement performance of the damped states is also studied.
