Quantum Teleportation in a Solid State System | John H. Reina

2 Jun 1999 | Journal: | Phys. Rev. A 63, 012303 (2000). The PRA version includes major changes. | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall quant-ph | Affiliation: | Oxford University | Abstract: | We propose a practical solid-state system capable of demonstrating quantum teleportation. The set-up exploits recent advances in the optical control of excitons in coupled quantum dots, in order to produce maximally-entangled Bell and Greenberger-Horne-Zeilinger (GHZ) states. Only two unitary transformations are then required: a quantum Controlled-Not gate and a Hadamard gate. The laser pulses necessary to generate the maximally-entangled states, and the corresponding unitary transformations, are given explicitly. | Source: | arXiv, cond-mat/9906034 | Services: | Forum | Review | PDF | Favorites |
