A Classical-Light Attack on Energy-Time Entangled Quantum Key Distribution, and Countermeasures

Abstract: Quantum key distribution (QKD) is an application of quantum mechanics that allows two parties to communicate with perfect secrecy. Traditional QKD uses polarization of individual photons, but the development of energytime entanglement could lead to QKD protocols robust against environmental effects. The security proofs of energy-time entangled QKD rely on a violation of the Bell inequality to certify the system as secure. This thesis shows that the Bell violation can be faked in energy-time entangled QKD proto… Show more
