Abstract How mixed can one component of a bi-partite system be initially and still become entangled through interaction with a thermalized partner? We address this question here. In particular, we consider the question of how mixed a two-level system and a field mode may be such that free entanglement arises in the course of the time evolution according to a Jaynes-Cummings type interaction. We investigate the situation for which the two-level system is initially in a mixed state taken from a… 

Entanglement dynamics in a non-Markovian environment: An exactly solvable model

We study the non-Markovian effects on the dynamics of entanglement in an exactly-solvable model that involves two independent oscillators each coupled to its own stochastic noise source. First, we

Exact dynamics of interacting qubits in a thermal environment: results beyond the weak coupling limit

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. Based on this mapping, exact numerical

Entanglement evolution of three-qubit mixed states in multipartite cavity?reservoir systems

We analyze the multipartite entanglement evolution of three-qubit mixed states composed of a GHZ state and a W state. For a composite system consisting of three cavities interacting with independent

Entanglement and measurement-induced nonlocality of mixed maximally entangled states in multipartite dynamics

The maximally entangled state can be in a mixed state as well as the well-known pure state. Taking the negativity as a measure of entanglement, we study the entanglement dynamics of bipartite, mixed

Temperature dependence of interaction-induced entanglement

Both direct and indirect weak nonresonant interactions are shown to produce entanglement between two initially disentangled systems prepared as a tensor product of thermal states, provided the

Entropy Growth and Formation of Stationary Entanglement due to Intrinsic Noise in the Two-Mode JC Model

We investigate the dynamics of the two-mode Jaynes-Cummings model with generalized nonlinear coupling including intrinsic noise as described by the Milburn equation. Based on a general analytic

Dynamical phase transitions and temperature-induced quantum correlations in an infinite spin chain

We study the dynamics of entanglement in the infinite asymmetric XY spin chain, in an applied transverse field. The system is prepared in a thermal equilibrium state (ground state at zero

On the preparation of pure states in resonant microcavities

Abstract We consider the time evolution of the radiation field (R) and a two-level atom (A) in a resonant microcavity in terms of the Jaynes-Cummings model with an initial general pure quantum state

Complementarity and Entanglement in Quantum Information Theory

The restrictions that nature places on the distribution of correlations in a multipartite quantum system play fundamental roles in the evolution of such systems, and yield vital insights into the

Energy as an entanglement witness for quantum many-body systems (15 pages)

We investigate quantum many-body systems where all low-energy states are entangled. As a tool for quantifying such systems, we introduce the concept of the entanglement gap, which is the difference

Entanglement and the factorization-approximation

Abstract:For a bi-partite quantum system defined in a finite dimensional Hilbert-space we investigate in what sense entanglement change and interactions imply each other. For this purpose we

Subsystem purity as an enforcer of entanglement.

TLDR
It is shown that entanglement can always arise in the interaction of an arbitrarily large system in any mixed state with a single qubit in a pure state, and the time and temperature variation of a lower bound on the amount of entanglements produced is found.

Dynamics of quantum entanglement

A model of discrete dynamics of entanglement of a bipartite quantum state is considered. It involves a global unitary dynamics of the system and periodic actions of local bistochastic or decaying

Volume of the set of separable states

The question of how many entangled or, respectively, separable states there are in the set of all quantum states is considered. We propose a natural measure in the space of density matrices %

The Jaynes-Cummings Model

Abstract The Jaynes-Cummings model (JCM), a soluble fully quantum mechanical model of an atom in a field, was first used (in 1963) to examine the classical aspects of spontaneous emission and to

Mixed-State Entanglement and Distillation: Is there a “Bound” Entanglement in Nature?

It is shown that if a mixed state can be distilled to the singlet form it must violate partial transposition criterion [A. Peres, Phys. Rev. Lett. 76, 1413 (1996)]. It implies that there are two

TLDR
It is shown that there exists a large class of initial states for which no entanglement will be created at all times between the system of salient interest and the environment.

Comparison of quantum and semiclassical radiation theories with application to the beam maser

Nonlocal correlations are generic in infinite-dimensional bipartite systems

It was recently shown that the nonseparable density operators for a bipartite system are trace norm dense if either factor space has infinite dimension. We show here that non-local states -- i.e.,

Computable measure of entanglement

TLDR
A measure of entanglement that can be computed effectively for any mixed state of an arbitrary bipartite system is presented and it is shown that it does not increase under local manipulations of the system.
