Generating multi-atom entangled W states via light-matter interface based fusion mechanism
(Nature Publishing Group, 2015-11-09)
W state is a key resource in quantum communication. Fusion technology has been proven to be a good candidate for preparing a large-size W state from two or more small-size W states in linear optical system. It is of great ...
Deterministic generation of large scale atomic W states
(Optical Soc Amer, 2016-05-30)
We present a deterministic scheme for generating large-scale atomic W states in a cavity QED system via a simple expansion mechanism, which is realized only by a detuned interaction between two identical atoms and a vacuum ...
Generating multi-photon W-like states for perfect quantum teleportation and superdense coding
(Springer New York LLC, 2016-05-06)
An interesting aspect of multipartite entanglement is that for perfect teleportation and superdense coding, not the maximally entangled W states but a special class of non-maximally entangled W-like states are required. ...
