Quantum cryptography 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]. I show some attacks, countermeasures, and the testbenches in this lab.

Vadim Makarov is a professor in quantum physics AND an election official in Russia.
On the quantum side, he heads quantum hacking labs at Vigo quantum communication center at the University of Vigo in Spain and at the Russian quantum center in Moscow, see http://www.vad1.com/lab/
On the classical side, he chases vote-riggers and hacks security bags.
