A New Solution to Detectable Byzantine Agreement Problem
Qin Su-Juan, Wen Qiao-yan, Luoming Meng, Fu-Chen Zhu · Communications in Theoretical Physics · 2009
We present a new quantum protocol for solving detectable Byzantine agreement problem between three parties by employing one quantum key distribution protocol. The protocol is suggested by a special four-qubit entangled state instead of singlet states, which shows that singlet states are not necessary to achieve detectable Byzantine agreement.
