When i take a coherent state ##|\alpha>## if ##\alpha -> 0## then the limit is the Fock state for n = 0. so ##|n = 0> = |\alpha = 0>##(adsbygoogle = window.adsbygoogle || []).push({});

The problem is that they seem to have different Wigner functions:

Where is the error?

Thanks.

Edit sorry, in the link the W function is for a (n = 1) Fock state. So no more problem.
