CQPToolkit

CQP Tool kit The system provides various components for integrating QKD into a security system. It's written in C++11 but uses GRPC interfaces so can be integrated with lots of different languages. Quick Start To run the software natively, ether: download and install the Ubuntu deb packages or...

One-Sided-DIQKD Using Any Pure Bipartite Entangled State Secure against All Attacks

Quantum Key Distribution QKD allows spatially separated parties to establish a secret key among themselves based on quantum principles. While QKD systems are being deployed worldwide, their reliance on trusted measurements makes them vulnerable. Moreover, existing protocols have largely focussed ...

Multi-Path Security in Quantum Networks with Trusted Nodes

Quantum communication networks promise information-theoretic security but this security collapses if intermediate relay nodes are compromised, a risk that grows sharply when compromised nodes cannot be identified. We address this twofold: first, we show that multi-path routing provides quantifiab...
