Use case: quantum communications
for a secure digital future
- Communications in the quantum era: Quantum networks will secure the world’s data against the threat of quantum hacking.
- Based on single photon emission and detection: If someone tries to intercept them, the laws of quantum physics reveal the intruder
Universal Plug and Play Sources are needed:
- for global deployment with high interoperability across industries and operators
Scalable sources are needed:
- without them, quantum networks are mere prototypes and cannot be deployed worldwide for governments and corporations
Deterministic sources are needed:
- for uncompromised protocol security and flexibility
