Teleportation of composite systems for communication and information processing
Sebastien G. R. Louis, Andrew D. Greentree, W. J. Munro +1
We describe two protocols for efficient data transmission using a single passive bus. Different types of interactions are obtained enabling deterministic transfer and teleportation…
Identifying a Two-State Hamiltonian in the Presence of Decoherence
Jared H. Cole, Andrew D. Greentree, Daniel K. L. Oi +3
Mapping the system evolution of a two-state system allows the determination of the effective system Hamiltonian directly. We show how this can be achieved even if the system is dec…
Precision characterisation of two-qubit Hamiltonians via entanglement mapping
Jared H. Cole, Simon J. Devitt, Lloyd C. L. Hollenberg
We show that the general Heisenberg Hamiltonian with non-uniform couplings can be characterised by mapping the entanglement it generates as a function of time. Identification of th…
Quantum information transport to multiple receivers
Andrew D. Greentree, Simon J. Devitt, Lloyd C. L. Hollenberg
The importance of transporting quantum information and entanglement with high fidelity cannot be overemphasized. We present a scheme based on adiabatic passage that allows for tran…
Identifying an Experimental Two-State Hamiltonian to Arbitrary Accuracy
Jared H. Cole, Sonia G. Schirmer, Andrew D. Greentree +3
Precision control of a quantum system requires accurate determination of the effective system Hamiltonian. We develop a method for estimating the Hamiltonian parameters for some un…
An algorithm for simulating the Ising model on a type-II quantum computer
J. H. Cole, L. C. L. Hollenberg, S. Prawer
Presented here is an algorithm for a type-II quantum computer which simulates the Ising model in one and two dimensions. It is equivalent to the Metropolis Monte-Carlo method and t…
