Polarization-randomized gateway against detector-blinding hacks of quantum key distribution

연구 분야: Cryptography

A quantum key distribution system -employing a key time-bin qubit and a security-pass polarization-randomized qubit- is shown to overcome a wide class of intercept-resend attacks adopting the use of faked-state light; including attacks based on blinding of single-photon avalanche detectors (SPADs).
