Practical measurement-device-independent quantum key distribution: theory and ex
Abstract: Quantum cryptography or quantum key distribution (QKD) can provide unconditional (i.e. information-theoretic) security based on the laws of quantum physics. It has been identified as the fi...

Quantum Journal Club： Effects of Reduced Measurement Independence on Bell-Based
Abstract: With the advent of quantum information, the violation of a Bell inequality is used to witness the absence of an eavesdropper in cryptographic scenarios such as key distribution and randomne...
