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…
Evaluating Relayed and Switched Quantum Key Distribution (QKD) Network Architectures
Antonis Selentis, Nikolas Makris, Alkinoos Papageorgopoulos +4
We evaluate the performance of two architectures for network-wide quantum key distribution (QKD): Relayed QKD, which relays keys over multi-link QKD paths for non-adjacent nodes, a…
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…
SMF Coupled Compact Ground Terminal with Advanced Filtering Towards Daylight C Band Satellite QKD
Argiris Ntanos, Aristeidis Stathis, Panagiotis Kourelias +14
We demonstrate a compact, high-isolation C-band optical ground terminal for satellite QKD, achieving more than 120 dB daylight background suppression and 135 dB crosstalk noise iso…
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.
