A low-noise single-photon detector for long-distance free-space quantum communication
Elena Anisimova, Dmitri Nikulov, Simeng Simone Hu +5
We build and test a single-photon detector based on a Si avalanche photodiode Excelitas 30902SH thermoelectrically cooled to -100 deg. C. Our detector has dark count rate below 1 H…
Mitigating radiation damage of single photon detectors for space applications
Elena Anisimova, Brendon L. Higgins, Jean-Philippe Bourgoin +7
Single-photon detectors in space must retain useful performance characteristics despite being bombarded with sub-atomic particles. Mitigating the effects of this space radiation is…
Laser annealing heals radiation damage in avalanche photodiodes
Jin Gyu Lim, Elena Anisimova, Brendon L. Higgins +3
Avalanche photodiodes (APDs) are a practical option for space-based quantum communications requiring single-photon detection. However, radiation damage to APDs significantly increa…
Airborne demonstration of a quantum key distribution receiver payload
Christopher J. Pugh, Sarah Kaiser, Jean-Philippe Bourgoin +8
Satellite-based quantum terminals are a feasible way to extend the reach of quantum communication protocols such as quantum key distribution (QKD) to the global scale. To that end,…
