Among various quantum-key-distribution (QKD) protocols, the round-robin differential-phase-
shift (RRDPS) protocol has a unique feature where its security is guaranteed without …

This paper proposes the first mediated authenticated differential phase shift quantum key
distribution (DPS-QKD) protocol. An untrusted third party is introduced to reduce the burden …

A novel quantum key distribution protocol based on the entanglement and dense coding is
proposed, in which the memory of the quantum state is not needed. Every four particles are …
