Based on entanglement swapping, a scheme for the secret sharing of an arbitrary two-particle entangled state is proposed. If the controllers do not co-operate with the eavesdropper, the eavesdropper's successful prob...

We propose a scheme to realize the nonlocal quantum entanglement of three three-level particles by using a threeparticle entangled state of three levels as a quantum channel with the aid of some local unitary transfor...

A scheme for remotely preparing a two-atom entangled state via entanglement swapping in cavity quantum electronic dynamics (QED) with the help of separate measurements is proposed. And the effect of cavity decay is ...
