Measuring the Squeezing Parameter for the Squeezed Number States by the Displaced Wigner Function

IICQI 2012

In this paper an experimental setup, which is proposed by Lutterbach and Davidovich, for non-demolition measurement of photon counting is applied to measure the displaced Wigner distribution function. Then the relation between the measured Wigner distribution function and the squeezing parameter is obtained. This method is applied for the determination of squeezing parameter of a squeezed number state.
