Dynamical phases for the evolution of the entanglement between two oscillators coupled to the same environment [PDF]
, 2009 We study the dynamics of the entanglement between two oscillators that are initially prepared in a general two-mode Gaussian state and evolve while coupled to the same environment.

Postponing Distillability Sudden Death in a Correlated Dephasing Channel
Entropy, 2020 We investigated the dynamics of a two-qutrit system in a correlated quantum channel. The partial correlations between consecutive actions of the channel can effectively postpone the phenomenon of distillability sudden death (DSD) and broaden the range of

Entanglemnt in nonlinear three-qubits Jaynes — Cummings
Вестник Самарского университета: Естественнонаучная серия, 2023 In this paper, we investigated the dynamics of entanglement of pairs of qubits in a system of three identical qubits that interact non-resonantly with the selected mode of a microwave resonator without loss with the Kerr medium by means of single-photon ...

Nonexistence of entanglement sudden death in dephasing of high NOON states [PDF]
Optics Letters, 2009 We study the dynamics of entanglement in continuous variable quantum systems. Specifically, we study the phenomena of entanglement sudden death (ESD) in general two-mode-N-photon states undergoing pure dephasing. We show that for these circumstances, ESD never occurs.

Entanglement dynamics of bipartite system in squeezed vacuum reservoirs
, 2010 Entanglement plays a crucial role in quantum information protocols, thus the dynamical behavior of entangled states is of a great importance. In this paper we suggest a useful scheme that permits a direct measure of entanglement in a two-qubit cavity ...

The entanglement dynamics of the bipartite quantum system: toward entanglement sudden death [PDF]
Journal of Physics A: Mathematical and Theoretical, 2008 We investigate the entanglement dynamics of bipartite quantum system between two qubits with the dissipative environment. We begin with the standard Markovian master equation in the Lindblad form and the initial state which is prepared in the extended Werner-like state: $ ^ _{AB}(0)$.

, 2011 Analyses of phenomena exhibiting finite-time decay of quantum entanglement have recently attracted considerable attention. Such decay is often referred to as sudden vanishing (or sudden death) of entanglement, which can be followed by its sudden ...

Alexandria Engineering Journal, 2023 We explore the quantum-memory assisted entropic uncertainty (QMA-EU), Jensen-Shannon coherence and entanglement dynamics in a Graphene sheet of disordered electrons in the presence of the intrinsic decoherence.
