Quantum correlations measured by measurement-induced disturbance (MID) in a two-qubit Heisenberg XY spin model with Dzialoshinskii—Moriya (DM) interaction under intrinsic decoherence are investigated. MID is studied under various circumstances and the influences of the external dependencies on the final quantum state which has stable MID are discussed. Two kinds of initial quantum states are considered as well as different conclusions. MID appears to decay periodically during the processing of…

Local quantum uncertainty in a two-qubit Heisenberg spin chain with intrinsic decoherence
Quantum correlation plays an important role in quantum information processing, for which various quantifiers have been proposed so far. In this paper, we address the dynamics of local quantum
Effect of intrinsic decoherence on entanglement of three polar molecules with two-dimensional rotation
Abstract The dynamic entanglement of three polar molecules with two-dimensional rotations is investigated under the influence of an electric field and intrinsic decoherence. The parameters of the

Decoherence and measurement-induced correlations
Decoherence arises from the interaction of a quantum system with the environment or, more precisely, from the measurement in which the environment ''measures'' the quantum system and establishes
Using measurement-induced disturbance to characterize correlations as classical or quantum
In contrast to the seminal entanglement-separability paradigm widely used in quantum information theory, we introduce a quantum-classical dichotomy in order to classify and quantify statistical

TLDR
A model for intrinsic decoherence in quantum mechanics is proposed, based on a simple modification of unitary Schrodinger evolution, with testable consequences including anomalous dispersion of a free particle, decay of oscillatory systems, destruction of interference-fringe visibility, and a phase shift of interference fringes.
Investigations into quantum correlation of coupled qubits in a squeezed vacuum reservoir
In this paper, we investigate the quantum correlation of coupled qubits which are initially in maximally entangled mixed states in a squeezed vacuum reservoir. We compare and analyze the effects of
Intrinsic decoherence in the atom-field interaction.
TLDR
It is shown that the intrinsic decoherence is responsible for deterioration of quantum coherence effects in this model, such as revivals of the atomic inversion in the Jaynes-Cummings model of atom-field interaction with nontrivial dynamics.
Evolution of spin entanglement and an entanglement witness in multiple-quantum NMR experiments
We investigate the evolution of entanglement in multiple-quantum (MQ) NMR experiments in crystals with pairs of close nuclear 1/2-spins. The initial thermodynamic equilibrium state of the system in a
Asymmetry of bipartite quantum discord
It is known from the analysis of the density matrix for bipartite systems that the quantum discord (as a measure of quantum correlations) depends on the particular subsystem chosen for the projective
Entanglement generation and entropy growth due to intrinsic decoherence in the Jaynes-Cummings model
We study how intrinsic decoherence leads to growing entropy and a strong degradation of the maximal generated entanglement in the multiquanta Jaynes–Cummings model. We find an exact solution of the
