Combining Error Verification and Privacy Amplification in Quantum Key Distribution

Quantum Key Distribution (QKD) protocols typically involve two separate steps of error-verification and privacy amplification. Both steps involve the application of a hash function sampled from a suitable hash family to classical data. A potentially simpler alternative is to implement a single-step hashing procedure, a...

Security framework for practical quantum key distribution with imperfect devices

This work presents a security proof for generic prepare-and-measure QKD protocols, including decoy-state BB84, with imperfect and imperfectly characterized sources and detectors using the marginal-constrained entropy accumulation theorem (MEAT).
