Quantum Teleportation via Hybrid Entangled States
Abstract:
In this paper, we study quantum teleportation of atomic states via a hybrid entangled state （HES） involving an atom and a cavity field. And we investigate how to implement controlled phase （CP） gates between atomic internal states and coherent states of cavity field. We also discuss the methods of distinguishing coherent states [±α〉 in a cavity. Finally, a brief discussion about the feasibility of this scheme in experiment is presented.[著者文摘]
Key words:
hybrid entangled states, quantum teleportation, controlled phase gates, discrimination of cavityfield coherent states
