Abstract

Superconductor-semiconductor hybrid devices are an evolving field, combining the technologically mature semiconductors with the unique properties of superconductors, utilized in quantum computing, information and communications. Radiative recombination of Cooper pairs in superconducting light-emitting diodes (SLED) results in superconductor-enhanced light emission. The theory behind this effect is based on a two-photon interaction with Cooper pairs, predicted to enable polarization-entangled photon pairs [1], two-photon amplification in waveguides [2] and Bell-state analyzers [3].

Summary form only given. Various applications in the rapidly growing field of quantum information science require reliable and effective quantum light sources. We observed superconducting proximity in semiconductor light-emitting diodes (Fig. 1). These hybrid structures were proposed by us as an efficient approach for generation of entangled photons, based on Cooper-pair luminescence in semiconductors, which does not require isolated emitters. Semiconductor quantum wells, remove the light-heavy-hole degeneracy, allowing efficient photon entanglement generation in simple electrically-driven structures, taking advantage of the superconducting macroscopic coherence [1]. Based on the developed theory we analyzed a new effect of enhanced light amplification in electrically-driven semiconductor-superconductor structures, including Cooper-pair based two-photon gain [2]. Moreover, we proposed 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.
