Quantum teleportation as the key strategy for quantum communication requires pure maximally shared entangled states among quantum nodes.In practice,quantum decoherence drastically degrades the shared entanglement duri...
Quantum teleportation has been developed to simultaneously realize the Hertz rate and the 64-km distance through fiber channels,which is essential to real-world application of quantum network.
In this work,we study the performance of one shot and concatenated deleting machines(DMs).We show that the output state of one shot DMs are mixed inseparable,and do not violate Bell's inequality but can be used as a t...
In this paper,we develop the teleportation scheme in[Zheng in Phys Rev A 69,064302,2004],in the sense that,we work in the strong atom-field coupling regime wherein the rotating wave approximation(RWA)is no longer vali...
