Entanglement generation is temperature-independent.

Finite temperature affects the time to reach a certain entanglement level.

The scheme is feasible for integrated optics applications.

Abstract

We propose a physical scheme to generate entangled light at high temperatures through the excitation of vacuum fluctuations of the electromagnetic field using periodic modulations of a refractive index of a ring resonator. We consider the processes of dissipation and decoherence resulting from the coupling of the system with an environment at finite temperature and show that the total amount of entanglement generated does not depend on the temperature, which only affects the time necessary for the system to produce such an amount of entanglement.
