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…
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…
