Enabling Shortwave-QKD in Short-Reach Networks: Impact of a Composite ODN Native to Telecom Applications
Mariana F. Ramos, Costin Luchian, Michael Hentschel +4
We deploy shortwave-QKD over short-reach in-house/datacom architectures and show that few-mode propagation and speckle-selective loss severely impact the QKD performance. We accomp…

Secure Multi-Party Biometric Verification using QKD assisted Quantum Oblivious Transfer
Mariana F. Ramos, Michael Hentschel, Federico Valbusa +7
We present a practical implementation of a secure multiparty computation application enabled by quantum oblivious transfer (QOT) on an entanglement-based physical layer. The QOT pr…

Datacom-Agnostic Shortwave QKD for Short-Reach Links
Mariana Ferreira Ramos, Marie-Christine Slater, Michael Hentschel +3
We investigate the co-existence of 852-nm and 1550-nm QKD with carrier-grade 4x25-Gb/s/ LANWDM over a short-reach interconnect. Shortwave QKD yields a higher key rate and is ins…
