Young, R. J. and Stevenson, R. M. and Shields, A. J. and Atkinson, P. and Cooper, K. and Ritchie, D. A. (2007) Entangled photons from the biexciton cascade of quantum dots. Journal of Applied Physics, 101 (8). -. ISSN 0021-8979Full text not available from this repository.
Single InAs quantum dots embedded in a planar cavity, formed by mismatched sets of GaAs/AlAs distributed Bragg reflectors, can be a useful source of triggered polarization-entangled photon pairs. We demonstrate this with a fidelity exceeding 70% for the expected entangled state. Quantum dot based devices may therefore be of great use in quantum communications and quantum information processing.
