Intrinsic phase operator of the Noh-Fougères-Mandel experiments
Berthold‐Georg Englert, Krzysztof Wódkiewicz, Peter Riegler · Physical Review A · 1995
We find the intrinsic Hermitiean phase operator associated with the Noh-Foug\`eres-Mandel apparatus. This is achieved by first identifying the corresponding phasor basis. Previous, alternative approaches are shown to be equivalent. Quantum analogs of trigonometric functions are discussed with the aid of their Glauber and Wigner representations.
