Phase uncertainties of a squeezed state

Physical Review A, 1994
We investigate various measures of phase uncertainty in their dependence on the average number of photons for the case of a phase squeezed state. We use the following three measures: (i) the geometrical uncertainty (\ensuremath{\delta}${\mathit{cphi}}_{\mathit{g}}$${)}^{2}$, (ii) the dispersion (\ensuremath{\delta}${\mathit{cphi}}_{\mathit{d}}$${)}^{2}$

On the Coherent States and the Squeezed States

Chinese Physics Letters, 1995
In this paper the coherent and the squeezed state of the bose field is written as a universal form by means of a projector which transforms the old vacuum state to the new vacuum state. The transformed vacuum state is the coherent state or the squeed state. Our result is equivalent to the original definitions.

Generating superposition of squeezed states and photon-added squeezed states

Physica Scripta
Abstract The scheme of an arrangement is considered for the preparation of some non-classical superposed states from squeezed states by using the optical parametric amplifier (OPA) apparatus, which is based on an idea recently proposed to generate photon-added states from the coherent states of light.

Squeezing Properties of the Generalized Multimode Squeezed States

Communications in Theoretical Physics, 2001
By means of the invariance of Weyl ordering under similar transformations we derive the explicit form of the generalized multimode squeezed states. Moreover, the completeness relation and the squeezing properties of the generalized multimode squeezed states are discussed.
