    "abstract": "Lo and Chau showed that an ideal quantum coin flipping protocol is\nimpossible. The proof was simply derived from the impossibility proof of\nquantum bit commitment. However, the proof still leaves the possibility of a\nquantum coin flipping protocol with arbitrary small bias.\n  In this paper, we show that a quantum coin flipping protocol with arbitrary\nsmall bias is impossible and show the lower bound of the bias of quantum coin\nflipping protocol.",
