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…

Reference-Beam Attacks against Twin-Field Quantum Key Distribution using Optical Injection Locking

Sergio Juárez, Alessandro Marcomini, Mikhail Petrov +5

Twin-Field Quantum Key Distribution (TF-QKD) has become a leading protocol to bring quantum communications to the national scale. The protocol requires the establishment of a share…

Edge-of-chaos enhanced quantum-inspired algorithm for combinatorial optimization

Hayato Goto, Ryo Hidaka, Kosuke Tatsumura

Nonlinear dynamical systems with continuous variables can be used for solving combinatorial optimization problems with discrete variables. Numerical simulations of them are also us…
