Sequential Attack Impairs Security in Device-independent Quantum Key
Distribution
Device-independent quantum key distribution (DI-QKD) leverages nonlocal correlations to securely establish cryptographic keys between two honest parties while making minimal assumptions about the underlying systems. The security of DI-QKD relies on the validation of quantum theory, with Bell violations ensuring the inherent unpredictability of the observed statistics, independent of the …
