Terrestrial readiness campaign for space-to-ground quantum communications with a space-qualified entangled photon-pair system
Gianluca De Santis, Jia Boon Chin, Srihari Sivasankaran +8
Realizing a global quantum internet relies on the deployment of robust satellite-based entanglement distribution links. While pioneering demonstrations have established the feasibi…
Thermo-mechanical design for a miniaturized quantum light source on board the SpooQy-1 CubeSat
Huai Ying Lim, Tom Vergoossen, Robert Bedington +8
This paper presents the thermo-mechanical design of the quantum light source on board SpooQy-1, a 3U CubeSat that was deployed from the International Space Station on 17th June 201…
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.…
SpooQySats: cubesats to demonstrate quantum key distribution technologies
James A. Grieve, Robert Bedington, Rakhitha C. M. R. B. Chandrasekara +1
Satellite-based QKD offers the potential to share highly secure encryption keys between optical ground stations all over the planet. SpooQySats is a programme for establishing the…
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…
Deploying quantum light sources on nanosatellites II: lessons and perspectives on CubeSat spacecraft
Robert Bedington, Edward Truong-Cao, Tan Yue Chuan +6
To enable space-based quantum key distribution proposals the Centre for Quantum Technologies is developing a source of entangled photons ruggedized to survive deployment in space a…
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…
