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.

Effects of quantum error correction on entanglement sudden death [PDF]
Quantum Information and Computation, 2014 We investigate the effects of error correction on non-local quantum coherence as a function of time, extending the study by Sainz and Bjork. We consider error correction of amplitude damping, pure phase damping and combinations of amplitude and phase damping as they affect both fidelity and quantum entanglement.

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.

Quantum discord and entanglement in grover search algorithm
Open Physics, 2016 Imperfections and noise in realistic quantum computers may seriously affect the accuracy of quantum algorithms. In this article we explore the impact of static imperfections on quantum entanglement as well as non-entangled quantum correlations in Grover ...

Entanglement dynamics during decoherence [PDF]
, 2009 The evolution of the entanglement between oscillators that interact with the same environment displays highly non-trivial behavior in the long time regime. When the oscillators only interact through the environment, three dynamical phases were identified

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
