High-quality entangled-photon pairs are one of key resources for quantum computing and quantum information technologies. Since the observation of entangled photon generation via a biexciton from a CuCl bulk crystal, entangled photon generation mediated by the biexciton has been extensively studied. Recently, the biexciton of a CuCl thin film in a microcavity was observed, whose radiative decay was two times faster than that in the absence of the cavity (the Purcell effect of a biexciton).
