Quantum Optics Jena GmbH

Quantum Optics Jena GmbH presents itself as a quantum technology company from Jena focused on secure communication solutions based on quantum optics and photonics. Its website says it develops quantum-safe communication solutions using quantum key distribution to protect sensitive data against eavesdropping and future quantum threats.

The company describes QKD as a way to exchange keys with immediate eavesdropping detection while integrating with existing network infrastructure. It also says its systems are designed for uses including government, defense, banking, and critical infrastructure, and that QKD and post-quantum cryptography can be combined as a layered security approach.

On its homepage, the company highlights a named system, ELVIS, and states that its solutions range from point-to-point links to more complex networks. The site also links investor relations content.
