Teleportation for atomic entangled state by entanglement swapping with separate measurements in cavity QED
Zheng-Yuan Xue, Ming Yang, You-Ming Yi, Zhuo-Liang Cao
Abstract
Experimentally feasible scheme for teleportation of atomic entangled state via entanglement swapping is proposed in cavity quantum electrodynamics (QED) without joint Bell-state measurement (BSM). In the teleportation processes the interaction between atoms and a single-mode nonresonant cavity with the assistance of a strong classical driving field substitute the joint measurements. The discussion of the scheme indicates that it can be realized by current technologies.
