Entanglement concentration for unknown atomic entangled states via entanglement swapping
arXiv:quant-ph/0411157 · doi:10.1103/PhysRevA.71.044302
Abstract
An entanglement concentration scheme for unknown atomic entanglement states is proposed via entanglement swapping in cavity QED. Because the interaction used here is a large-detuned one between two driven atoms and a quantized cavity mode, the effects of the cavity decay and thermal field have been eliminated. These advantages can warrant the experimental feasibility of the current scheme.
