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.

Open quantum system dynamics of X-states: Entanglement sudden death and sudden birth
Modern Physics Letters A, 2023 In this paper, the origin of disentanglement for two specific sub-classes of [Formula: see text]-states namely maximally nonlocal mixed states (MNMSs) and maximally entangled mixed states (MEMSs) is investigated analytically for a physical system consisting of two spatially separated qubits interacting with a common vacuum bath.

Non-classical correlation of cascaded photon pairs emitted from quantum dot
, 2011 We studied the quantum correlation between the photon pairs generated by biexciton cascade decays of self-assembled quantum dots, and determined the temperature behavior associated with so-called sudden change of the quantum correlation. The relationship

Delayed (sudden) birth of entanglement [PDF]
, 2008 The concept of time delayed creation of entanglement by the dissipative process of spontaneous emission is investigated. A threshold effect for the creation of entanglement is found that the initially unentangled qubits can be entangled after a finite ...

Gaussian quantum entanglement in curved spacetime
Results in Physics, 2023 The influence of Hawking radiation on quantum entanglement for bimodal Gaussian states near a Schwarzschild black hole is investigated. It is shown that for a thermal squeezed state of a bimodal bosonic system the Hawking radiation reduces and even can ...

Entanglement dynamics of two-bipartite system under the influence of dissipative environments
, 2010 An experimental scheme is suggested that permits a direct measure of entanglement in a two-qubit cavity system. It is realized in the cavity-QED technology utilizing atoms as flying qubits.
