Most people assume encrypted data is safe forever. It isn’t. Adversaries are already collecting encrypted communications today with the expectation that future quantum computers will be able to decrypt them. For data that needs to remain confidential for years or decades, that is a very real problem. That is why we built Quantum Optics Jena. In this documentary, we explain how quantum key distribution uses light to generate encryption keys and reveal any attempt to intercept them. No security technology is magic. But our technology offers something fundamentally different: protection rooted in the laws of physics rather than assumptions about how hard a mathematical problem is to solve. Proud to see our team featured and grateful to everyone helping turn this technology into something practical. Thank you Yves Nill for introducing the QOJ team to the world on Europe’s Foundry! We are very proud of this documentary, and it was a pleasure working with you.
Most encrypted data has an expiry date. Adversaries are already collecting sensitive information today with the expectation that future #QuantumComputers will be able to decrypt it. This “harvest now, decrypt later” threat means data with a long shelf life—financial records, government communications, critical infrastructure data—could be exposed years from now. That is the challenge Quantum Optics Jena GmbH is working to solve. In a new documentary, our team explains to Europe's Foundry how quantum key distribution (QKD) uses the laws of physics to generate encryption keys and detect any attempt to intercept them. Rather than relying solely on mathematical assumptions, #QKD creates keys using quantum states of light. Any eavesdropping attempt disturbs those states and is immediately detectable. The result is a fundamentally different approach to securing communications against both current and future threats. Quantum-safe security is moving from theory to deployed infrastructure. #Quantum #Cybersecurity
