Steering, Entanglement, Nonlocality, and the EPR Paradox
H. M. Wiseman, S. J. Jones, A. C. Doherty
The concept of steering was introduced by Schrodinger in 1935 as a generalization of the EPR paradox for arbitrary pure bipartite entangled states and arbitrary measurements by one…
Quantum Control of a Single Qubit
Agata M. Branczyk, Paulo E. M. F. Mendonca, Alexei Gilchrist +2
Measurements in quantum mechanics cannot perfectly distinguish all states and necessarily disturb the measured system. We present and analyse a proposal to demonstrate fundamental…
Study of the Distillability of Werner States Using Entanglement Witnesses and Robust Semidefinite Programs
Reinaldo O. Vianna, Andrew C. Doherty
We use Robust Semidefinite Programs and Entanglement Witnesses to study the distillability of Werner states. We perform exact numerical calculations which show 2-undistillability i…
Bounds on Quantum Correlations in Bell Inequality Experiments
Yeong-Cherng Liang, Andrew C. Doherty
Bell inequality violation is one of the most widely known manifestations of entanglement in quantum mechanics; indicating that experiments on physically separated quantum mechanica…
Better Bell Inequality Violation by Collective Measurements
Yeong-Cherng Liang, Andrew C. Doherty
The standard Bell inequality experiments test for violation of local realism by repeatedly making local measurements on individual copies of an entangled quantum state. Here we inv…
Quantum Computation as Geometry
Michael A. Nielsen, Mark R. Dowling, Mile Gu +1
Quantum computers hold great promise, but it remains a challenge to find efficient quantum circuits that solve interesting computational problems. We show that finding optimal quan…
Optimal control, geometry, and quantum computing
Michael A. Nielsen, Mark R. Dowling, Mile Gu +1
We prove upper and lower bounds relating the quantum gate complexity of a unitary operation, U, to the optimal control cost associated to the synthesis of U. These bounds apply for…
Entanglement of indistinguishable particles in condensed matter physics
Mark R. Dowling, Andrew C. Doherty, Howard M. Wiseman
The concept of entanglement in systems where the particles are indistinguishable has been the subject of much recent interest and controversy. In this paper we study the notion of…
