| Abstract(in English) | In quantum coin flipping, if a dishonest player exists, there is a bias e, that Prob(c = 0) ≦ 1/2 + ε and Prob(c = 1) ≦ 1/2 + ε when two players are about to reach an agreement on a value c. But, Lo and chau show that there is no quantum protocol for perfect quantum coin flipping in terms of a bias (i.e., quantum coin flipping with bias 0). However, this still leaves the possibility that there might be quantum protocols with an arbitrarily small bias and many studies have been made about it. A protocol proposed by Ambainis is one of them and the bias of this protocol is 1/4 Fukuda, Soshi and Miyaji extended the protocol with 3 quantum states to a 4 states protocol and discussed. In this paper, we construct n states quantum coin flipping and discuss the biases in several cases. |
