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…
The photon pair source that survived a rocket explosion
Zhongkan Tang, Rakhitha Chandrasekara, Yue Chuan Tan +3
We report on the performance of a compact photon pair source that was recovered intact from a failed space launch. The source had been embedded in a nanosatellite and was designed…
Deploying quantum light sources on nanosatellites I: lessons and perspectives on the optical system
Rakhitha Chandrasekara, Tang Zhongkan, Tan Yue Chuan +5
The Small Photon Entangling Quantum System is an integrated instrument where the pump, photon pair source and detectors are combined within a single optical tray and electronics pa…
Space qualified nanosatellite electronics platform for photon pair experiments
Cliff Cheng, Rakhitha Chandrasekara, Yue Chuan Tan +1
We report the design and implementation of a complete electronics platform for conducting a quantum optics experiment that will be operated on board a 1U CubeSat (a 10 x 10 x 10 cm…
Radiation tolerance of opto-electronic components proposed for space-based quantum key distribution
Tan Yue Chuan, Rakhitha Chandrasekara, Cliff Cheng +1
Plasma in low earth orbit can damage electronic components and potentially jeopardise the scientific missions in space. Predicting the accumulated damage and understanding the comp…
Silicon avalanche photodiode operation and lifetime analysis for small satellites
Yue Chuan Tan, Rakhitha Chandrasekara, Cliff Cheng +1
Silicon avalanche photodiodes (APDs) are sensitive to operating temperature fluctuations and are also susceptible to radiation flux expected in satellite-based quantum experiments.…
