Using weak values to experimentally determine "negative probabilities" in a two-photon state with Bell correlations
B. L. Higgins, M. S. Palsson, G. Y. Xiang +2
Bipartite quantum entangled systems can exhibit measurement correlations that violate Bell inequalities, revealing the profoundly counter-intuitive nature of the physical universe.…
Optical Quantum Computation
T. C. Ralph, G. J. Pryde
We review the field of Optical Quantum Computation, considering the various implementations that have been proposed and the experimental progress that has been made toward realizin…
Experimental EPR-Steering of Bell-local States
D. J. Saunders, S. J. Jones, H. M. Wiseman +1
Entanglement is the defining feature of quantum mechanics, and understanding the phenomenon is essential at the foundational level and for future progress in quantum technology. Th…
Noiseless Linear Amplification and Distillation of Entanglement
G. Y. Xiang, T. C. Ralph, A. P. Lund +2
The idea of signal amplification is ubiquitous in the control of physical systems, and the ultimate performance limit of amplifiers is set by quantum physics. Increasing the amplit…
How to perform the most accurate possible phase measurements
D. W. Berry, B. L. Higgins, S. D. Bartlett +3
We present the theory of how to achieve phase measurements with the minimum possible variance in ways that are readily implementable with current experimental techniques. Measureme…
Demonstration of a simple entangling optical gate and its use in Bell-state analysis
N. K. Langford, T. J. Weinhold, R. Prevedel +5
We demonstrate a new architecture for an optical entangling gate that is significantly simpler than previous realisations, using partially-polarising beamsplitters so that only a s…
Measuring Controlled-NOT and two-qubit gate operation
Andrew G. White, Alexei Gilchrist, Geoffrey J. Pryde +3
Accurate characterisation of two-qubit gates will be critical for any realisation of quantum computation. We discuss a range of measurements aimed at characterising a two-qubit gat…
