Non-classicality indicators are widely applied to describe the physical properties of quantum states. One category of these indicators is defined in terms of negativities portion of Wigner distribution function. These indicators are not indicating to some quantum properties, e.g.: squeezing. Because the squeezing operations don’t effect on, the amount of negativities of Wigner distribution functions. Therefore the non-classicality indicators, e.g.: Kenfak or Benedict, which are working based on the negativities of distribution functions, cannot recognize the squeezing properties. In this paper a non-classicality indicator is introduced, in terms of the radial and angular distribution of absolute value of Wigner distribution function, which can recognize the squeezing properties, e.g.: squeezing parameter and squeezing angle. This non-classicality indicator is applied for the squeezed photonic states. We show that this indicator can evaluate the number of photons as well as the squeezing parameter and squeezing angle
Keywords: Non-classicality indicators, Wigner distribution function, squeezing operations
