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…
