  - "Semiconductor quantum dots are promising sources for polarization-entangled photons.
    As an alternative\r\nto the usual cascaded biexciton-exciton emission, direct
    two-photon emission from the biexciton can be used.\r\nWith a high-quality optical
    resonator tuned to half the biexciton energy, a large proportion of the photons\r\ncan
    be steered into the two-photon emission channel. In this case the degree of polarization
    entanglement is\r\ninherently insensitive to the exciton fine-structure splitting.
    In the present work we analyze the biexciton emission\r\nwith particular emphasis
    on the influence of coupling of the quantum-dot cavity system to its environment.\r\nEspecially
    for a high-quality cavity, the coupling to the surrounding semiconductormaterial
    can open up additional\r\nphonon-assisted decay channels. Our analysis demonstrates
    that with the cavity tuned to half the biexciton energy,\r\nthe potentially detrimental
    influence of the phonons on the polarization entanglement is strongly suppressed—high\r\ndegrees
    of entanglement can still be achieved. We further discuss spectral properties
    and statistics of the emitted\r\ntwin photons.@eng"
