Towards Hyperentanglement via Semiconductor Two-Photon Emission
Alex Hayat, Pavel Ginzburg, David Neiman, Serge Rosenblum, Meir Orenstein · International Conference on Quantum Information · 2008
A novel phenomenon of semiconductor two-photon emission is presented experimentally. Based on this effect, we propose implementations of compact highly-efficient room-temperature sources of entangled photons (inter-band transitions in a microcavity) and hyperentangled photons (inter-subband transitions).
