Automated verification of countermeasure against detector-control attack in quantum key distribution
Polina Acheva, Konstantin Zaitsev, Vladimir Zavodilenko +3
Attacks that control single-photon detectors in quantum key distribution using tailored bright illumination are capable of eavesdropping the secret key. Here we report an automated…
Protocols for healing radiation-damaged single-photon detectors suitable for space environment
Joanna Krynski, Nigar Sultana, Youn Seok Lee +2
Single-photon avalanche detectors (SPADs) are well-suited for satellite-based quantum communication because of their advantageous operating characteristics as well as their relativ…
Characterisation of state-preparation uncertainty in quantum key distribution
Anqi Huang, Akihiro Mizutani, Hoi-Kwong Lo +2
To achieve secure quantum key distribution, all imperfections in the source unit must be incorporated in a security proof and measured in the lab. Here we perform a proof-of-princi…
Protecting fiber-optic quantum key distribution sources against light-injection attacks
Anastasiya Ponosova, Daria Ruzhitskaya, Poompong Chaiwongkhot +3
A well-protected and characterised source in a quantum key distribution system is needed for its security. Unfortunately, the source is vulnerable to light-injection attacks, such…
Faking photon number on a transition-edge sensor
Poompong Chaiwongkhot, Jiaqiang Zhong, Anqi Huang +3
We study potential security vulnerabilities of a single-photon detector based on superconducting transition-edge sensor. In a simple experiment, we show that an adversary could fak…
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…
