Frontiers in Quantum Science and Technology, 2023 We investigate the dynamics of a maximally entangled mixed state (MEMS) under the action of correlated noise channels. The channel acts in a way that its successive uses are correlated. We have studied the MEMS properties, including quantum coherence and

Influence of Stark Shift on Entanglement of Two Qubits in the Two-Photon Tavis-Cummings Model
EPJ Web of Conferences, 2015 Considering two-atom degenerate two-photon Tavis-Cummings model, we investigate the entanglement between two atoms prepared initially in the coherent disentangled states and cavity field prepared in few-photon Fock state, and study the effect of the ...

New Journal of Physics, 2013 We demonstrate an exact mapping of a class of models of two interacting qubits in thermal reservoirs to two separate problems of spin–boson-type systems.

Entanglement sudden death in qubit–qutrit systems [PDF]
Physics Letters A, 2008 We demonstrate the existence of entanglement sudden death (ESD), the complete loss of entanglement in finite time, in qubit-qutrit systems. In particular, ESD is shown to occur in such systems initially prepared in a one-parameter class of entangled mixed states and then subjected to local dephasing noise.

Two distinguishable impurities in BEC: squeezing and entanglement of two Bose polarons
SciPost Physics, 2019 We study entanglement and squeezing of two uncoupled impurities immersed in a Bose-Einstein condensate. We treat them as two quantum Brownian particles interacting with a bath composed of the Bogoliubov modes of the condensate.

Entanglement dynamics in anti-PT-symmetric systems
Physical Review Research, 2022 In the past years, many efforts have been made to study various noteworthy phenomena in both parity-time (PT) and anti-parity-time (APT) symmetric systems.

Thermal entanglement in the three-qubit Tavis-Cummings model with Kerr nonlinearity
Компьютерная оптикаWe obtained a solution of the Liouville equation for a system of three identical qubits interacting without detuning with a thermal field of a cavity with a Kerr medium, for two type of initial pure genuine W-entangled qubits states.
