Generation of Werner-like stationary states of two qubits in a thermal reservoir

TL;DR

This paper investigates how two qubits evolve in a thermal reservoir, revealing the existence of nontrivial stationary states that generalize Werner states under thermal conditions.

Contribution

It introduces a thermal generalization of Werner states as asymptotic solutions in the dynamics of two qubits in a thermal reservoir.

Findings

Existence of nontrivial asymptotic states in strong correlation regimes

Thermal generalization of Werner states identified

Stationary entanglement properties analyzed

Abstract

The dynamics of entanglement between two-level atoms immersed in a common photon reservoir at finite temperature is investigated. It is shown that in the regime of strong correlations there are nontrivial asymptotic states which can be interpreted in terms of thermal generalization of Werner states.
