Determination of the Wigner function from photon statistics
arXiv:quant-ph/9904089
Abstract
We present an experimental realisation of the direct scheme for measuring the Wigner function of a single quantized light mode. In this method, the Wigner function is determined as the expectation value of the photon number parity operator for the phase space displaced quantum state.
