Influence of Initial Entangled States on the Temperature-Dependent CHSH Inequality

Quantum Physics 2023-09-15 v1

Abstract

We demonstrate that the temperature affects the validity of the CHSH inequality in an open bipartite two-qubit system. Specifically, for initial entangled states within the decoherence-free subspace (DFS), the CHSH inequality remains temperature-independent. In contrast, other entangled states exhibit a temperature threshold beyond which the inequality holds.
