Opinion bubbles in the quantum Buridan's ass problem
Leonid Chaichenets, Jaroslav Novotný, Igor Jex +2
The quantum Buridan's ass problem concerns a network of interconnected nodes in which transitions between the nodes are governed by the laws of quantum mechanics. In such situation…
Tailored two-photon correlation and fair-sampling: a cautionary tale
Jacquiline Romero, Daniel Giovannini, Daniel Tasca +2
We demonstrate an experimental test of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality which seemingly exhibits correlations beyond the limits imposed by quantum mechanics. I…
Determining the dimensionality of bipartite orbital-angular-momentum entanglement using multi-sector phase masks
D. Giovannini, F. M. Miatto, J. Romero +3
The Shannon dimensionality of orbital angular momentum (OAM) entanglement produced in spontaneous parametric down-conversion can be probed by using multi-sector phase analysers. We…
Securing a Quantum Key Distribution Network Using Secret Sharing
Stephen M. Barnett, Simon J. D. Phoenix
We present a simple new technique to secure quantum key distribution relay networks using secret sharing. Previous techniques have relied on creating distinct physical paths in ord…
Extending the Reach of QKD Using Relays
Stephen M. Barnett, Simon J. D. Phoenix
One of the obstacles to deployment of QKD solutions has been the distance limitation. Solutions using relays have been proposed but these rely on link-by-link key establishment. We…
Joint measurements and Bell inequalities
Wonmin Son, Erika Andersson, Stephem M. Barnett +1
Joint quantum measurements of non-commuting observables are possible, if one accepts an increase in the measured variances. A necessary condition for a joint measurement to be poss…
