Observable-Level Framework for Finite-Key Security in Coherent-One-Way Quantum Key Distribution

Practical security analysis of Coherent-One-Way COW quantum key distribution requires optical-device modeling, finite experimental statistics, and security inference to be treated consistently without conflating assumptions. We present a modular observable-level simulation framework organized...

Processing Entangled Links into Secure Cryptographic Keys

The following paper presents a holistic approach to the processing of entangled links within entanglement based quantum key distribution protocols, whose security relies on the Bell inequality. We investigate the interactions, and the collective impact, of the whole processing chain on the final...
