Entanglement demonstration on board a nano-satellite
Aitor Villar, Alexander Lohrmann, Xueliang Bai +14
Global quantum networks for secure communication can be realised using large fleets of satellites distributing entangled photon-pairs between ground-based nodes. Because the cost o…
Satellite quantum communications when man-in-the-middle attacks are excluded
Tom Vergoossen, Robert Bedington, James A Grieve +1
An application of quantum communications is the transmission of qubits to create shared symmetric encryption keys in a process called Quantum Key Distribution (QKD). Contrary to pu…
Satellite constellations for trusted node QKD networks
Tom Vergoossen, Sergio Loarte, Robert Bedington +2
Quantum key distribution from satellites becomes particularly valuable when it can be used on a large network and on-demand to provide a symmetric encryption key to any two nodes.…
Demonstrating Miniaturised, entangled photon-pair sources on board nano satellites to enable future QKD missions
Rakhitha C. M. R. B. Chandrasekara, Robert Bedington, Xueliang Bai +7
We report on our progress developing highly-miniaturised, polarisation-entangled, photon pair sources for CubeSats. We have a correlated photon-pair source in orbit in the NUS Gala…
Progress in satellite quantum key distribution
Robert Bedington, Juan Miguel Arrazola, Alexander Ling
Quantum key distribution (QKD) is a family of protocols for growing a private encryption key between two parties. Despite much progress, all ground-based QKD approaches have a dist…
Extreme environmental testing of a rugged correlated photon source
James A. Grieve, Robert Bedington, Alexander Ling
Experiments in long distance quantum key distribution have motivated the development of ruggedised single photon sources, capable of producing useful correlations even when removed…
