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…
