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.
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…
