Is composite noise necessary for sudden death of entanglement?

open access: yesResults in Physics, 2013
The finite time disentanglement or entanglement sudden death, when only one part of the composite system is subjected to a single noise, is examined. While it is shown that entanglement sudden death can occur when a part of the entangled mixed state is subjected to either amplitude noise or phase noise, local action of either of them does not cause ...

Entanglement dynamics of two-qubit system in different types of noisy channels

open access: yes, 2008
In this paper, we study entanglement dynamics of a two-qubit extended Werner-like state locally interacting with independent noisy channels, i.e., amplitude damping, phase damping and depolarizing channels.

Dynamics of quantum entanglement in the reservoir with memory effects

open access: yes, 2012
The non-Markovian dynamics of quantum entanglement is studied by the Shabani-Lidar master equation when one of entangled quantum systems is coupled to a local reservoir with memory effects. The completely positive reduced dynamical map can be constructed

Dynamics of entanglement of separable three-qubit states in the Tavis — Cummings multiphoton model

open access: yesВестник Самарского университета: Естественнонаучная серия
In this work we study in detail the generalized Tavis — Cummings model, in which three identical qubits are trapped in a lossless single-mode resonator and interact resonantly with the quantized thermal electromagnetic field of this resonator by means of

DYNAMICS AND ENTANGLEMENT OF A QUANTUM DOT-CAVITY SYSTEM COUPLED BY A NON-LINEAR OPTICAL INTERACTION

open access: yesMomento, 2017
We propose a simple theoretical model for a dissipative quantum dot-microcavity system interacting with a non-linear optical interaction. The Lindblad master equation formalism is considered to study the full dynamics for both weak and strong coupling ...

Dynamics of entanglement of qubits in not-resonant two-qubit Jaynes — Cummings model in the presence of dipole-dipole and Ising interactions

open access: yesВестник Самарского университета: Естественнонаучная серия
In this paper, we study the dynamics of a system consisting of two identical qubits interacting non-resonantly with a single-mode field of an ideal resonator in the presence of direct dipole-dipole and Ising interactions between the qubits.
