Hacking Measurement-Device-Independent Quantum Key Distribution

The security of practical quantum key distribution QKD systems is fundamentally constrained by vulnerabilities of single-photon detectors. Measurement-device-independent quantum key distribution MDI-QKD was proposed to remove this limitation by allowing all measurements to be performed by a...

The Practical Issues of Side-Channel-Secure Quantum Key Distribution

Quantum Key Distribution QKD leverages the principles of quantum mechanics to provide theoretically unconditional security for cryptographic key sharing. However, practical implementations remain vulnerable due to non-ideal devices and potential security loopholes at both the source and detection...
