Robustness of fiber-optic attenuators to 1061-nm sub-nanosecond pulsed laser radiation in quantum key distribution systems
Daria Ruzhitskaya, Irina Zhluktova, Anastasiya Ponosova +10
The security of quantum key distribution (QKD) systems relies on the physical integrity of their components. While laser-damage attacks (LDAs) using high-power continuous-wave (cw)…
Spectral side channels of wavelength-division multiplexer in quantum key distribution under laser damage
Binwu Gao, Junxuan Liu, Ekaterina Borisova +8
In the transmitter of a quantum key distribution (QKD) system, a wavelength-division multiplexer (WDM) is typically used to combine quantum and synchronization signals and is direc…
Fiber-optic power limiter device based on carbon nanotubes
Ekaterina Borisova, Anastasiya Ponosova, Natalia Arutyunyan +4
We experimentally demonstrate a power limiter based on single-walled carbon nanotubes dispersed in a polymer matrix. This simple fiber-optic device permanently increases its attenu…
Wide-spectrum security of quantum key distribution
Hao Tan, Mikhail Petrov, Weiyang Zhang +5
Implementations of quantum key distribution (QKD) need vulnerability assessment against loopholes in their optical scheme. Most of the optical attacks involve injecting or receivin…
Pulsed laser attack at 1061 nm potentially compromises quantum key distribution
Anastasiya Ponosova, Irina Zhluktova, Daria Ruzhitskaya +6
Quantum key distribution systems offer cryptographic security, provided that all their components are thoroughly characterised. However, certain components might be vulnerable to a…
Optical-pumping attack on a quantum key distribution laser source
Maxim Fadeev, Anastasiya Ponosova, Qingquan Peng +3
We report a new type of vulnerability in practical implementations of quantum key distribution systems. We show that it is possible to increase the pulse energy of a source laser d…
