A scheme for transferring an unknown atomic entangled state via cavity quantum electrodynamics
Wu Tao, Ye Liu, 倪致祥 · Chinese Physics · 2006
In this paper, we propose a scheme for transferring an unknown atomic entangled state via cavity quantum electrodynamics (QED). This scheme, which has a successful probability of 100 percent, does not require Bell-state measurement and performing any operations to reconstruct an initial state. Meanwhile, the scheme only involves atom–field interaction with a large detuning and does not require the transfer of quantum information between the atoms and cavity. Thus the scheme is insensitive to the cavity field states and cavity decay. This scheme can also be extended to transferring an entangled state of n-atom.
