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…
Elementary Excitations of a Bose-Einstein Condensate in an Effective Magnetic Field
D. R. Murray, P. Öhberg, Damiá Gomila +1
We calculate the low energy elementary excitations of a Bose-Einstein Condensate in an effective magnetic field. The field is created by the interplay between light beams carrying…
Polarisation rotation of slow light with orbital angular momentum in ultracold atomic gases
J. Ruseckas, G. Juzeliunas, P. Ohberg +1
We consider the propagation of slow light with an orbital angular momentum (OAM) in a moving atomic medium. We have derived a general equation of motion and applied it in analysing…
