C-NOT three-gates performance by coherent cavity field and its optimized quantum applications

C-NOT three-gates performance by coherent cavity field and its optimized quantum applications A new realization model of controlled-not (C-NOT) three gates operations, between two atoms and coherent light. The proposed interaction model allows to earn more interaction time compared with the C-NOT two gates model of the reference work. As investigation of the obtained results, we enhance and optimize a recent teleportation work via coherent cavity field, by using less cavities number during the teleportation process. A higher probability have seen in the coherent state teleportation compared with the reference teleportation protocol (single photon teleportation). Furthermore, a generation and teleportation scheme of multipartite GHZ-type entangled coherent states is established. We note that more efficiency is given to our scheme because of simplicity of homodyne detection for coherent light. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Quantum Information Processing Springer Journals
