Robust quantum key distribution with imperfections in state preparation and characterization

Quantum key distribution (QKD) offers an approach for secure communication over quantum channels, based on the principles of quantum mechanics. However, the inevitable imperfections in QKD systems can introduce critical vulnerabilities, posing significant challenges to the deployment of QKD in terms of both practical s...

Afterpulse analysis for practical phase-matching quantum key distribution

Reconfigurable Quantum Key Distribution

This work proves that the security of the proposed scheme can be reduced to that of standard QKD protocols with MUBs and full quantum state preparation, thereby inheriting the established security proofs of existing QKD protocols.

Device-Independent Quantum Secret Sharing With Advanced Random Key Generation Basis Enhanced by Advantage Distillation

This work innovatively integrates tripartite advantage distillation (AD) with an advanced random key generation basis strategy and effectively improves the protocol’ s noise tolerance, reduces the global detection effciency threshold, and significantly extends the maximum secure communication distance.
