Engineering Entanglement in Cavity Quantum Electrodynamical Systems

Phenomenon of entanglement was justly referred by Erwin Schrdinger as the characteristic trait of the quantum theory. On one hand, the phenomenon helped a lot to clarify the conceptual foundations of the theory. On the other hand, the very same nonlocal, counterintuitive correlations that bind entangled entities are now being employed as a backbone resource for most of the quantum informatics tasks including cryptography, teleportation, entanglement swapping, quantum computation and many others. Therefore controlled engineering of entangled states becomes vitally important. Present monograph introduces the the concept of entanglement in its historical background and further reviews the related work done employing tools based on Cavity Quantum Electrodynamics. The work also deals with four theoretical proposals for the cavity QED based generation of a variety of entangled atomic and cavity field entangled states including Bell, W, NOON, cluster and graph states.
