Abstract

Positive-P and Wigner representations for quantum-optical systems with nonorthogonal modes were discussed. The operator correspondences connecting the underlying density operator with the corresponding Fokker-Planck equations were developed. Both representations were compared by calculating the tunneling times for an unstable resonator optical parametric oscillator.
