Quantum Key Distribution

Our filed patent covers the invention of a new Quantum Key Distribution (QKD) protocol which is designed to work with the state-of-the-art quantum photonic hardware. When combined with cutting-edge quantum detectors, it provides true unconditional security guaranteed by the laws of physics (device-independent).

Information transfer will be safe even if all hardware components are compromised by an eavesdropper. This is a unique feature which eliminates the vulnerabilities present in some other commercially available QKD systems.

Additionally, if some hardware components are known to be trusted, our protocol can run in an alternative mode with higher communication rates, comparable to the best solutions available on the market. This adaptability allows the user to tailor the protocol to their individual needs

Fiber – based QKD

Quantum key distribution over optical fiber allows two parties to share a secret key for data encryption encoded as a quantum state – and quantum physics proves that it is impossible for it to be compromised!

Free – space QKD

Quantum key distribution can be performed across free space using radio towers or drones as intermediate stations, without any need of fibers – providing secure communications to two parties separated by larger distances.

QKD over satellites

Quantum key distribution can even be done between two remote locations on Earth using satellites – forming a global network of secure quantum communication.
