Quantum cryptography and its certification against attacks (WHY2025)
I briefly explain quantum cryptography. It is unbreakable in principle, but its real implementations have vulnerabilities arising from equipment imperfections. Certification standards [1] and accredited labs are being
established that can test commercial products for these flaws. I explain how we have analysed a commercial quantum key distribution system for loopholes, patched them, and designed tests for the certification lab [2].
