Relayed-QKD and switched-QKD networks performance comparison considering physical layer QKD limitations

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 perform better for short distances and at large networks.Comment: 3 page

O-band QKD link over a multiple ONT loaded carrier-grade GPON for FTTH applications

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 access network with multiple ONTs to emulate real-life FTTH operational deployments.Comment: 3 page
