Decoy state quantum key distribution with imperfect source
Anqi Huang, Shi-Hai Sun, Zhihong Liu +1
The decoy state protocol has been considered to be one of the most important methods to protect the security of quantum key distribution (QKD) with a weak coherent source. Here we…
Invisible Trojan-horse attack
Shihan Sajeed, Carter Minshull, Nitin Jain +1
We demonstrate the experimental feasibility of a Trojan-horse attack that remains nearly invisible to the single-photon detectors employed in practical quantum key distribution (QK…
Space QUEST mission proposal: Experimentally testing decoherence due to gravity
Siddarth Koduru Joshi, Jacques Pienaar, Timothy C. Ralph +42
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum properties, such as entanglement, may exhi…
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…
