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…
Tracking capacitance of liquid crystal devices to improve polarization rotation accuracy
Rakhitha Chandrasekara, Kadir Durak, Alexander Ling
We report a capacitance tracking method for achieving arbitrary polarization rotation from nematic liquid crystals. By locking to the unique capacitance associated with the molecul…
