Superconductor semiconductor quantum optoelectronic devices:

Various applications in the rapidly growing field of quantum information science require reliable and efficient quantum light sources. We observed superconducting proximity in semiconductor light-emitting diodes. These hybrid structures were proposed by us as an efficient approach for generation of entangled photons, based on Cooper-pair luminescence in semiconductors. We study a new effect of enhanced light amplification in electrically-driven semiconductor-superconductor structures, including Cooper-pair based two-photon gain. Moreover, we investigate a compact and highly-efficient scheme for a complete Bell-state analysis using two-photon absorption in a superconducting proximity region of a semiconductor avalanche photodiode. This Cooper-pair based two-photon absorption results in a strong detection preference of a specified entangled state.
