Our quantum key distribution systems are based on standard coherent telecommunication technology, operated at the quantum limit. Using integrated photonics, we achieve scalability.


We provide quantum key distribution systems (QKD) as well as key management systems (KMS) to secure your infrastructure from emerging threats such as quantum computers.


We are a start-up located in Germany. Our excellent team with decades of experience in quantum science and industry works with you to deliver the best solution.
