Quantum-based key distribution with entangled photons for cyber security
By fighting quantum challenges with quantum technologies, we develop and deliver quantum key distribution (QKD) systems based on entangled photons. This allows the implementation of cyber security solutions on the fundamentals of physical laws. We enable a quantum added value.

Quantum Key Distribution Systems
The building blocks for the »Elvis« QKD systems consist of the entangled photon pair source »HD«, the polarization analyzing and control sub-systems »PAM«, and our unique quantum protocol implementation »LLC«, which is based on the BBM92 protocol. The modularity enables cost-efficient implementation for data-center connections and communication networks as well as experimental setups. Short distance and free space QKD systems at 800 nm wavelength and long-distance fiber-network systems at 1300 nm and 1500 nm are available.
