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…
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…
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…
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…
O-band QKD link over a multiple ONT loaded carrier-grade GPON for FTTH applications
N. Makris, A. Ntanos, A. Papageorgopoulos +10
We have successfully integrated an O-band commercial Quantum-Key-Distribution (QKD) system over a lit GPON testbed that replicates a carrier-grade Fiber-to-the-Home (FTTH) optical…
