Phys. Rev. A 69, 022315 (2004) [9 pages]Optimal processing of quantum information via W-type entangled coherent statesReceived 14 September 2003; revised 15 October 2003; published 23 February 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. © 2004 The American Physical Society URL:
