A Method for the Measurement of Photons Number and Squeezing Parameter in a Quantum Cavity
Figure 1
The Wigner function is plotted versus for . , , , and are the Wigner distribution functions for , respectively. The Wigner distribution functions at the origin have only two values for both the even and odd numbers of photons. Outside the origin, for example, at , values of the Wigner distribution functions are not the same for different number of photons.
