Quantum-Level Crosstalk Characterization of a 16x16 MEMS Optical Switch for Dynamic Quantum Communications
Persefoni Konteli, Nikolas Makris, Grigoris Anastasiou +2
We present an all-to-all quantum-level crosstalk characterization of a commercial 16x16 MEMS optical switch for multi-user quantum communications using SNSPDs, correlating experime…
Dynamic Switched Quantum Key Distribution Network with PUF-based authentication
Persefoni Konteli, Nikolaos Makris, Evgenia Niovi Sassalou +7
We demonstrate a centrally controlled dynamic switched-QKD network, with integrated PUF-based dynamic authentication for each QKD link. The performance of the dynamic switched-QKD…
Time-bin Phase and Polarization based QKD systems performance analysis over 16Km Aerial Fibers
Persefoni Konteli, Nikolaos Makris, Konstantinos Tsimvrakidis +5
We analyze the performance of Time-bin Phase and Polarization based QKD systems on mixed 14Km underground and 16Km of aerial fiber using plug-and-play commercial QKD systems.
Field demonstration of a fully managed, L1 encrypted 3-node network with hybrid relayed-QKD and centralized symmetric classical key management
N. Makris, A. Papageorgopoulos, K. Tsimvrakidis +19
We successfully demonstrated a fully-managed, field-deployed, three-node QKD ring network with L1-OTNsec encryption, that employs a hybrid scheme of QKD and classical yet quantum-s…
Relayed-QKD and switched-QKD networks performance comparison considering physical layer QKD limitations
N. Makris, A. Papageorgopoulos, P. Konteli +4
We experimentally evaluate the SKR generation for unoptimized QKD pairs in switched QKD and compare the performance of the switched-QKD with relayed-QKD networks to reveal they per…
