Graphical Methods in Device-Independent Quantum Cryptography [PDF]

Quantum, 2019
We introduce a framework for graphical security proofs in device-independent quantum cryptography using the methods of categorical quantum mechanics. We are optimistic that this approach will make some of the highly complex proofs in quantum cryptography

Weak Randomness Analysis of Measurement-Device-Independent Quantum Key Distribution with Finite Resources

Photonics, 2022
The ideal quantum key distribution (QKD) protocol requires perfect random numbers for bit encoding and basis selecting. Perfect randomness is of great significance to the practical QKD system. However, due to the imperfection of practical quantum devices,

Finite-Key Analysis of 1-Decoy Method Quantum Key Distribution with Intensity Fluctuation

Applied Sciences, 2022
The decoy state quantum key distribution (QKD) protocol is proven to be an effective strategy against the photon number splitting attack. It was shown that the 1-decoy state protocol, easier to implement in the practical QKD system, outperforms the 2 ...
