Squeezing Enhanced Two Phase Estimation With N Particle W States
Simultaneous estimation of two optical phases in a three‐mode interferometer assisted by optical parametric amplification (OPA) is investigated. The normally ordered characteristic function formalism is employed to derive analytical expressions for all photon number moments of the output state, allowing explicit evalua...
