Quasiprobability distributions in open quantum systems: Spin-qubit systems

TL;DR: In this paper, the authors provide a comprehensive analysis of quasiprobability distributions for spin-qubit systems under general open system effects, including both pure dephasing as well as dissipation.
Journal ArticleDOI

Dynamics of entanglement in two-qubit open system interacting with a squeezed thermal bath via dissipative interaction

TL;DR: In this article, the dynamics of entanglement in a two-qubit system interacting with a squeezed thermal bath via a dissipative system-reservoir interaction with the system and reservoir assumed to be in a separable initial state was studied by making use of concurrence as well as a recently introduced measure of mixed state entenglement via a probability density function.
Journal ArticleDOI

Dynamics of entanglement in Two-Qubit Open System Interacting with a Squeezed Thermal Bath via Dissipative interaction

TL;DR: In this paper, the dynamics of entanglement in a two-qubit system interacting with a squeezed thermal bath via a dissipative system-reservoir interaction with the system and reservoir assumed to be in a separable initial state was studied.
Journal ArticleDOI

Entanglement dynamics in two-qubit open system interacting with a squeezed thermal bath via quantum nondemolition interaction

TL;DR: In this paper, the dynamics of entanglement in a two-qubit system interacting with an initially squeezed thermal environment via aquantum non-demolition system-reservoir interaction was analyzed.
Journal ArticleDOI

Quasiprobability distributions in open quantum systems: spin-qubit systems

TL;DR: In this paper, the effect of both quantum non-demolition (QND) and dissipative open quantum systems on the evolution of a number of spin QDs is investigated, leading to a clear understanding of quantum to classical transition in a host of realistic physical scenarios.
