Query: Sampling quantum phase space with squeezed states   We study the application of squeezed states in a quantum optical scheme for
direct sampling of the phase space by photon counting. We prove that the
detection setup with a squeezed coherent probe field is equivalent to the
probing of the squeezed signal field with a coherent state. An example of the
Schroedinger cat state measurement shows that the use of squeezed states allows
one to detect clearly the interference between distinct phase space components
despite losses through the unused output port of the setup.
