Entanglement from thermal black body radiation

Abstract

Two non--interacting quantum systems which couple to a common environment with many degrees of freedom initially in thermal equilibrium can become entangled due to the indirect interaction mediated through this heat bath. I examine here the dynamics of reservoir induced entanglement for a heat bath consisting of a thermal electro--magnetic radiation field, such as black body radiation or the cosmic microwave background, and show how the effect can be understood as result of an effective induced interaction.

major modifications, including: addition of a section on the effective induced interaction; modified statements on quasi-instantaneous RIE; changed titel and updated reference 17
