Sub-shot-noise-limited fiber-optic quantum receiver
M. L. Shcherbatenko, M. S. Elezov, D. V. Sych +1
We experimentally demonstrate a quantum receiver based on Kennedy scheme for discrimination between two phase-modulated weak coherent states. The receiver is assembled entirely fro…

A countermeasure against bright-light attack on superconducting nanowire single-photon detector in quantum key distribution
Mikhail Elezov, Roman Ozhegov, Gregory Goltsman +1
We present an active anti-latching system for superconducting nanowire single-photon detectors. We experimentally test it against a bright-light attack, previously used to compromi…
