Quantum hacking - Vadim Makarov

Quantum cryptography and quantum communications, although perfectly secure in theory, suffer from equipment imperfections that leave possibilities for practical attacks on today's implementations. I will introduce these attacks on an example of the detector controllability loophole (for both avalanche photodiode and superconducting nanowire single-photon detectors) and discuss approaches to countermeasures. I will also show how laser damage to system components can enable eavesdropping.
