Practical Countermeasure Against Attacks Exploiting Detection Efficiency Mismatch in Quantum Key Distribution
Ben J. Taylor, Peter R. Smith, James F. Dynes +4
We demonstrate a practical countermeasure against a well-known class of attacks on quantum key distribution (QKD) systems that exploit detection efficiency mismatch, where the rece…

Phase noise characterisation of a 2-km Hollow-Core Nested Antiresonant Nodeless Fibre for Twin-Field Quantum Key Distribution
Mariella Minder, Sophie Albosh, Obada Alia +5
The performance of quantum key distribution (QKD) is heavily dependent on the physical properties of the channel over which it is executed. Propagation losses and perturbations in…

Autonomous Recognition of Erroneous Raw Key Bit Bias in Quantum Key Distribution
Matt Young, Marco Lucamarini, Stefano Pirandola
As Quantum Key Distribution technologies mature, it is pertinent to consider these systems in contexts beyond lab settings, and how these systems may have to operate autonomously.…
