A new Hilbert space approach to the multimode squeezing of light
Klaus Mølmer, W. Słowikowski · Journal of Physics A Mathematical and General · 1988
The Hilbert space of one-photon states is introduced and used for an investigation of some basic principles of squeezing. Regarding the one-photon space as the underlying structure of the fields, the authors introduce parametrisations that simplify calculations considerably, and discuss how phase sensitivity, characteristic for squeezing, reveals itself in the one-photon space.
