Testing random-detector-efficiency countermeasure in a commercial system reveals a breakable unrealistic assumption
Anqi Huang, Shihan Sajeed, Poompong Chaiwongkhot +3
In the last decade, efforts have been made to reconcile theoretical security with realistic imperfect implementations of quantum key distribution (QKD). Implementable countermeasur…
Creation of backdoors in quantum communications via laser damage
Vadim Makarov, Jean-Philippe Bourgoin, Poompong Chaiwongkhot +7
Practical quantum communication (QC) protocols are assumed to be secure provided implemented devices are properly characterized and all known side channels are closed. We show that…
Attacks exploiting deviation of mean photon number in quantum key distribution and coin tossing
Shihan Sajeed, Igor Radchenko, Sarah Kaiser +5
The security of quantum communication using a weak coherent source requires an accurate knowledge of the source's mean photon number. Finite calibration precision or an active mani…
Random Variation of Detector Efficiency: A Countermeasure against Detector Blinding Attacks for Quantum Key Distribution
Charles Ci Wen Lim, Nino Walenta, Matthieu Legre +2
In the recent decade, it has been discovered that QKD systems are extremely vulnerable to side-channel attacks. In particular, by exploiting the internal working knowledge of pract…
A fast and versatile QKD system with hardware key distillation and wavelength multiplexing
Nino Walenta, Andreas Burg, Dario Caselunghe +17
We present a 625 MHz clocked coherent one-way quantum key distribution (QKD) system which continuously distributes secret keys over an optical fibre link. To support high secret ke…
Experimental plug&play quantum coin flipping
Anna Pappa, Paul Jouguet, Thomas Lawson +5
Performing complex cryptographic tasks will be an essential element in future quantum communication networks. These tasks are based on a handful of fundamental primitives, such as…
