Quantum Entanglement and Teleportation of Quantum-Dot States in Microcavities

抄録

Generation and control of quantum entanglement are studied in an equivalent-neighbor system of spatially-separated semiconductor quantum dots coupled by a single-mode cavity field. Generation of genuinely multipartite entanglement of qubit states realized by conduction-band electron-spin states in quantum dots is discussed. A protocol for quantum teleportation of electron-spin states via cavity decay is briefly described. [DOI: 10.1380/ejssnt.2007.51]
