Continuous-variable entanglement adjustable by phase fluctuation and classical pumping field in a correlated emission laser seeded with squeezed light
We present the influence of phase fluctuations on the entanglement and intensity of the
radiation produced by a correlated-emission laser. The three-level atoms are initially …

Use of discrete Wigner functions in the study of decoherence of a system of superconducting flux-qubits
The persistence of coherence of a system of superconducting flux-qubits, in the presence of
an ensemble of electrons, is analysed. The time evolution of the system is solved exactly …

Entanglement and Mixedness of a Superconducting Qubit Coupled to an Open Superconducting Cavity
ABA Mohamed, H Eleuch - Journal of Russian Laser Research, 2016 - Springer
We investigate entanglement and mixedness of a superconducting qubit coupled to the
damped cavity field. We introduce a new measure for the mixedness and find that the phase …

Time evolution of statistical properties of a radiation field described by a density operator that interpolates between pure and mixing states
CJS Ferreira, TM Silva, B Baseia - The European Physical Journal B, 2019 - Springer
In this work, we consider a different model of density operator and a heuristic procedure that
interpolates a photonic system from pure to mixed states. It is interpreted as if, during the …

Nonclassical Features of Intra-Cavity and Transmitted Fields in a Coherently-Pumped Correlated-Emission Laser with Injected Thermal Light†
We discuss effects of phase fluctuations and thermal light on the entanglement, squeezing,
and intensity of the two-mode intra-cavity and transmitted fields generated by a coherently …
