Quantum key distribution overcoming practical correlated intensity fluctuations
Abstract Intensity correlations between neighbouring pulses open a prevalent yet often overlooked security loophole in decoy-state quantum key distribution (QKD). As a solution, we present and experimentally demonstrate an intensity-correlation-tolerant QKD protocol that mitigates the negative effec...
