Optimal processing of quantum information viaW-type entangled coherent states
Nguyen Ba An · Physical Review A · 2004
Optimized probabilistic teleportation and remote symmetric entangling of an arbitrary logical qubit are studied using particular forms of W-type entangled coherent states. Of interest is the fact that, while the teleportation can alternatively be performed by the GHZ-type entangled coherent states, the remote symmetric entangling strictly requires those of the W type.
