Phase-correlation-free quantum key distribution source operating at gigahertz rates
Shashank Kumar, Alessandro Marcomini, Loïc Millet +8
Phase randomization is essential for the security of practical decoy-state quantum key distribution (QKD) systems. Commonly, implementations rely on laser sources which are either…
Quantum Key Distribution with Efficient Post-Quantum Cryptography-Secured Trusted Node on a Quantum Network
Yoann Piétri, Pierre-Enguerrand Verdier, Baptiste Lacour +13
Quantum Key Distribution (QKD) enables two distant users to exchange a secret key with information-theoretic security, based on the fundamental laws of quantum physics. While it is…
Enhanced Detection Rate and High Photon-Number Efficiencies with a Scalable Parallel SNSPD
Lorenzo Stasi, Towsif Taher, Giovanni V. Resta +3
Since their inception, superconducting nanowire single-photon detectors have been enabling quantum optical applications and the rise of the photonic quantum industry. The evolution…
GHz detection rates and dynamic photon-number resolution with superconducting nanowire arrays
Giovanni V. Resta, Lorenzo Stasi, Matthieu Perrenoud +5
Superconducting-nanowire single-photon detectors (SNSPDs) have enabled the realization of several quantum optics technologies thanks to their high detection efficiency, low dark-co…
Satellite-Based Quantum Key Distribution in the Presence of Bypass Channels
Masoud Ghalaii, Sima Bahrani, Carlo Liorni +9
The security of prepare-and-measure satellite-based quantum key distribution (QKD), under restricted eavesdropping scenarios, is addressed. We particularly consider cases where the…
Fast Single Photon Detectors and real-time Key Distillation: Enabling High Secret Key Rate QKD Systems
Fadri Grünenfelder, Alberto Boaron, Matthieu Perrenoud +11
Quantum Key Distribution has made continuous progress over the last 20 years and is now commercially available. However, the secret key rates (SKR) are still limited to a few Mbps.…
