Entanglement as a signature of quantum chaos
Xiaoguang Wang, Shohini Ghose, Barry C Sanders +1
We explore the dynamics of entanglement in classically chaotic systems by considering a multiqubit system that behaves collectively as a spin system obeying the dynamics of the qua…
Electronic coherence theory
Stephen D. Bartlett, Barry C. Sanders, William D. Oliver +1
We withdraw our paper as the factorizability of the correlation functions is unproven.
Tripartite Quantum State Sharing
Andrew M. Lance, Thomas Symul, Warwick P. Bowen +2
We demonstrate a multipartite protocol to securely distribute and reconstruct a quantum state. A secret quantum state is encoded into a tripartite entangled state and distributed t…
On improving single photon sources via linear optics and photodetection
Dominic W. Berry, Stefan Scheel, Barry C. Sanders +1
In practice, single photons are generated as a mixture of vacuum with a single photon with weights 1-p and p, respectively; here we are concerned with increasing p by directing mul…
Direct observation of non-classical photon statistics in parametric downconversion
Edo Waks, Eleni Diamanti, Barry C. Sanders +2
We employ a high quantum efficiency photon number counter to determine the photon number distribution of the output field from a parametric downconverter. The raw photocount data d…
Numerical Analysis of the Capacities for Two-Qubit Unitary Operations
Dominic W. Berry, Barry C. Sanders
We present numerical results on the capacities of two-qubit unitary operations for creating entanglement and increasing the Holevo information of an ensemble. In all cases tested,…
