Entangled-Photon Generation in Biexcitonic Cavity QED

Abstract

We present a new concept of entangled photon generation via biexciton from a quantum-well embedded in a microcavity. The coupled states of the biexciton and cavity photons play an important role in the entangled photon generation. In fact, a suitable design of the level scheme of the coupled states can considerably enhance the generation process. We present the optimal condition for entangled photon generation in terms of the biexcitonic cavity quantum electrodynamics (QED).
