This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

Decoherence is a subject of great importance in quantum mechanics, particularly in the
fields of quantum optics, quantum information processing and quantum computing. Quantum …

The supersymmetric connection that exists between the Jaynes-Cummings (JC) and anti-
Jaynes Cummings (AJC) models in quantum optics is unraveled entirely. A new method is …

We study the possibility of reconstructing the quantum state of light in a cavity subject to
dissipation. We pass atoms, also subject to decay, through the cavity and surprisingly show …

We introduce quantum states associated with single phase space points in the Wigner
formalism for finite-dimensional spaces. We consider both continuous and discrete Wigner …

We show that it is possible to reconstruct the quantum state of light in a cavity subject to
dissipation at finite temperature. By passing atoms through the cavity it is shown that the …

We present a method for the direct measurement of the Wigner characteristic function of a
thermalizing harmonic oscillator that is completely inaccessible for control or measurement …

We propose a witness operation for the nonclassical character of a harmonic oscillator state.
The method does not require state reconstruction. For all harmonic oscillator states that are …

We study the atom-field interaction at finite temperature and in the dispersive regime. We
show that the master equation for this sytem may be solved with the use of superoperator …

We introduce a method for testing quantum correlations in terms of quasiprobability
functions in the presence of noise. We analyze the effects of measurement imperfection and …
