The results are well described quantitatively by a probabilistic model that includes two decay paths for a biexciton through a non-degenerate pair of one-exciton states, with the polarization of the emitted photons depending on the decay path. The results show that spin non-degeneracy due to quantum-dot asymmetry is a significant obstacle to the realization of an entangled-photon generation device.", "revisions": [ { "version": "v2", "updated": "2002-07-25T01:52:05.000Z" } ], "analyses": { "keywords": [ "single quantum dot", "polarization-correlated photon pairs", "single inas quantum dot", "decay path", "entangled-photon generation device" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
