Improving the security of arbitrated quantum signature protocols
Zhiwei Sun, Ruigang Du, Dongyang Long
Arbitrated quantum signatures (AQS), for signing quantum message, have been proposed. It was claimed that the AQS schemes could guarantee unconditional security. However, in this p…

Semi-quantum key distribution protocol using Bell state
Zhiwei Sun, Ruigang Du, Dongyang Long
A quantum key distribution protocol with classical Bob based on polarization entangled photon pairs is presented. It approximates a single photon and exploited the inherent randomn…

Quantum key distribution with limited classical Bob
Zhiwei Sun, Ruigang Du, Dongyang Long
Two QKD protocols with limited classical Bob who performs only limited classical operations (preparing a (fresh) qubit in the classical basis and send it or doing nothing) are pres…
