The squeezed generalized amplitude damping channel
R. Srikanth, Subhashish Banerjee
Squeezing of a thermal bath introduces new features absent in an open quantum system interacting with an uncorrelated (zero squeezing) thermal bath. The resulting dynamics, governe…
Phase Diffusion in Quantum Dissipative Systems
Subhashish Banerjee, R. Srikanth
We study the dynamics of the quantum phase distribution associated with the reduced density matrix of a system for a number of situations of practical importance, as the system evo…
Phase diffusion pattern in quantum nondemolition systems
Subhashish Banerjee, Joyee Ghosh, R. Ghosh
We quantitatively analyze the dynamics of the quantum phase distribution associated with the reduced density matrix of a system, as the system evolves under the influence of its en…
Dynamics of decoherence without dissipation in a squeezed thermal bath
Subhashish Banerjee, R. Ghosh
We study a generic open quantum system where the coupling between the system and its environment is of an energy-preserving quantum nondemolition (QND) type. We obtain the general…
