Quantum Key Distribution System for High-Security Data Protection
Future-Proof Protection Against Quantum Computer Threats
Fraunhofer HHI's Quantum Key Distribution (QKD) system provides long-term secure protection for sensitive data and communication applications. The powerful system seamlessly integrates into modern telecommunications infrastructures and uses both fiber optic and free-space transmissions to distribute cryptographic keys quickly and securely.
Time to digital converter with sub nanosecond resolution
A versatile measurement device for digitizing events in time domain with a resolution down to 0.1 nanoseconds.
Fraunhofer HHI’s Timetagger is a versatile measurement device with multiple input channels allowing digitizing the time of events with a resolution of 100 ps. Switching threshold and hysteresis could be set for any input channel. The digitized events could be read by a network interface.
Single-Mode Optical Antennas for High-Speed and Quantum Communication
Free-Space Laser Links as Flexible Fiber Alternatives
The single-mode optical antennas enable bidirectional data transmission in the optical C-band and are compatible with DWDM technology. They serve as over-the-air bridges for classical and quantum optical fiber-based communication, ideal for last-mile connections and high-speed point-to-point links. Utilizing a multi-aperture approach, they offer high robustness against atmospheric influences and scalable reach.
