Experimental Verification of Anisotropic Invariance for Three-Qubit States

Jie Zhu, Meng-Jun Hu, Shuming Cheng +4

We experimentally test the recently predicted anisotropic invariance properties of pure three-qubit states, via generation and measurement of polarisation-path entangled three-qubi…

On the dynamics of initially correlated open quantum systems: theory and applications

Gerardo A. Paz-Silva, Michael J. W. Hall, Howard M. Wiseman

We show that the dynamics of any open quantum system that is initially correlated with its environment can be described by a set of (or less) completely positive maps, where d is t…

Experimental validation of quantum steering ellipsoids and tests of volume monogamy relations

Chao Zhang, Shuming Cheng, Li Li +8

The set of all qubit states that can be steered to by measurements on a correlated qubit is predicted to form an ellipsoid---called the quantum steering ellipsoid---in the Bloch ba…

Relaxed Bell Inequalities with Arbitrary Measurement Dependence for Each Observer

Andrew S. Friedman, Alan H. Guth, Michael J. W. Hall +2

Bell's inequality was originally derived under the assumption that experimenters are free to select detector settings independently of any local "hidden variables" that might affec…

Nonlocality in Bell's theorem, in Bohm's theory, and in Many Interacting Worlds theorising

Mojtaba Ghadimi, Michael J. W. Hall, Howard M. Wiseman

'Locality' is a fraught word, even within the restricted context of Bell's theorem. As one of us has argued elsewhere, that is partly because Bell himself used the word with differ…

Entropic Heisenberg limits and uncertainty relations from the Holevo information bound

Michael J. W. Hall

Strong and general entropic and geometric Heisenberg limits are obtained, for estimates of multiparameter unitary displacements in quantum metrology, such as the estimation of a ma…
