Interferometric Tests of Teleportation
T. C. Ralph
We investigate a direct test of teleportation efficacy based on a Mach-Zehnder interferometer. The analysis is performed for continuous variable teleportation of both discrete and…
Entanglement Manipulation and Concentration
R. T. Thew, W. J. Munro
We introduce a simple, experimentally realisable, entanglement manipulation protocol for exploring mixed state entanglement. We show that for both non-maximally entangled pure, and…
Large-N solutions of the Heisenberg and Hubbard-Heisenberg models on the anisotropic triangular lattice: application to CsCuCl and to the layered organic superconductors -(BEDT-TTF)X
C. H. Chung, J. B. Marston, Ross H. McKenzie
We solve the Sp(N) Heisenberg and SU(N) Hubbard-Heisenberg models on the anisotropic triangular lattice in the large-N limit. These two models may describe respectively the magneti…
Separable states are more disordered globally than locally
M. A. Nielsen, J. Kempe
A remarkable feature of quantum entanglement is that an entangled state of two parties, Alice (A) and Bob (B), may be more disordered locally than globally. That is, S(A) > S(A,B),…
The Quantum Josephson Hamiltonian In The Phase Representation
J. R. Anglin, P. Drummond, A. Smerzi
The quantum Josephson Hamiltonian of two weakly linked Bose-Einstein condensates is written in an overcomplete phase representation, thus avoiding the problem of defining a Hermiti…
Non-Markovian homodyne-mediated feedback on a two-level atom: a quantum trajectory treatment
Jin Wang, H. M. Wiseman, G. J. Milburn
Quantum feedback can stabilize a two-level atom against decoherence (spontaneous emission), putting it into an arbitrary (specified) pure state. This requires perfect homodyne dete…
