Tripartite Quantum State Sharing
Andrew M. Lance, Thomas Symul, Warwick P. Bowen +2
We demonstrate a multipartite protocol to securely distribute and reconstruct a quantum state. A secret quantum state is encoded into a tripartite entangled state and distributed t…

Unity gain and non-unity gain quantum teleportation
W. P. Bowen, N. Treps, B. C. Buchler +4
We investigate continuous variable quantum teleportation. We discuss the methods presently used to characterize teleportation in this regime, and propose an extension of the measur…
