Environment Induced Bipartite Entanglement

Abstract

Recently, a sufficient condition on the structure of the Kossakowski-Lindblad master equation has been given such that the generated reduced dynamics of two qubits results entangling for at least one among their initial separable pure states. In this paper we study to which extent this condition is also necessary. Further, we find sufficient conditions for bath-mediated entanglement generation in higher dimensional bipartite open quantum systems.
