Quantum Key Distribution, integrated on chip

Our QKD Products

Two PIC-based QKD solutions

Our QKD portfolio addresses both terrestrial fibre networks and satellite-based quantum communication

PIC-based QKD over Fibre + PQC

Quantum Key Distribution over fibre using a Photonic Integrated Circuit architecture, with a PQC add-on for a combined quantum and post-quantum security approach.

Satellite QKD System

A satellite-based QKD system extending secure key distribution beyond terrestrial fibre networks, with PIC technology supporting the compact quantum photonic hardware needed for satellite applications.

Terrestrial QKD

Quantum Key Distribution over Terrestrial fibre

Quantum key distribution (QKD) provides a way of sharing secret keys in quantum status. By leveraging the inherent qualities of quantum status through phase encodeing it promises secure data transfer that is immune to eavesdropping.

Apart from enhancing the security of communication networks, our QKD approach simplifies the hardware requirements and thereby facilitates practical and scalable QKD systems.
