Optimal cloning for finite distributions of coherent states
P. T. Cochrane, T. C. Ralph, A. Dolinska
We derive optimal cloning limits for finite Gaussian distributions of coherent states, and describe techniques for achieving them. We discuss the relation of these limits to state…
Tailoring teleportation to the quantum alphabet
P. T. Cochrane, T. C. Ralph
We introduce a refinement of the standard continuous variable teleportation measurement and displacement strategies. This refinement makes use of prior knowledge about the target s…
Conditional two mode squeezed vacuum teleportation
P. T. Cochrane, T. C. Ralph, G. J. Milburn
We show, by making conditional measurements on the Einstein-Podolsky-Rosen (EPR) squeezed vacuum, that one can improve the efficacy of teleportation for both the position differenc…
Teleportation with the entangled states of a beam splitter
P. T. Cochrane, G. J. Milburn
We present a teleportation protocol based upon the entanglement produced from Fock states incident onto a beam splitter of arbitrary transmissivity. The teleportation fidelity is a…
Teleportation using coupled oscillator states
P. T. Cochrane, G. J. Milburn, W. J. Munro
We analyse the fidelity of teleportation protocols, as a function of resource entanglement, for three kinds of two mode oscillator states: states with fixed total photon number, nu…
Macroscopically distinct quantum superposition states as a bosonic code for amplitude damping
P. T. Cochrane, G. J. Milburn, W. J. Munro
We show how macroscopically distinct quantum superposition states (Schroedinger cat states) may be used as logical qubit encodings for the correction of spontaneous emission errors…
