Scheme for direct measurement of a general two-qubit Hamiltonian

Simon J. Devitt, Jared H. Cole, Lloyd C. L. Hollenberg

The construction of two-qubit gates appropriate for universal quantum computation is of enormous importance to quantum information processing. Building such gates is dependent on a…

Quantum gate for Q switching in monolithic photonic bandgap cavities containing two-level atoms

Andrew D. Greentree, J. Salzman, Steven Prawer +1

Photonic bandgap cavities are prime solid-state systems to investigate light-matter interactions in the strong coupling regime. However, as the cavity is defined by the geometry of…

Information free quantum bus for generating stabiliser states

Simon J. Devitt, Andrew D. Greentree, Lloyd C. L. Hollenberg

Efficient generation of spatially delocalised entangled states is at the heart of quantum information science. Generally flying qubits are proposed for long range entangling intera…

Multiplayer quantum Minority game with decoherence

Adrian P. Flitney, Lloyd C. L. Hollenberg

A quantum version of the Minority game for an arbitrary number of agents is considered. It is known that when the number of agents is odd, quantizing the game produces no advantage…

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…

Spin transport and quasi 2D architectures for donor-based quantum computing

L. C. L. Hollenberg, A. D. Greentree, A. G. Fowler +1

Through the introduction of a new electron spin transport mechanism, a 2D donor electron spin quantum computer architecture is proposed. This design addresses major technical issue…

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…
