Abstract: In a recent paper, Lo and Chau explain how to break a family of quantum bit commitment schemes, and they claim that their attack applies to the 1993 protocol of Brassard, Cr'epeau, Jozsa and Langlois (BCJL). The intuition behind their attack is correct, and indeed they expose a weakness common to all proposals of a certain kind, but the BCJL protocol does not fall in this category. Nevertheless, it is true that the BCJL protocol is insecure, but the required attack is more subtle. Here... (Update)

.... for tasks such as bit commitment [BCJL93] but those proofs were later discovered to be awed, since bit commitment was proven impossible [May96, LC97a, May97, LC96, LC97b, BCMS98] There have also been several works on quanutm coin tossing. Although arbitrarily small error is...
...the commitment. A cold rain fell on the scientific community when unconditional security for quantum bit commitment was proven impossible [19, 20, 18]. Though unconditional security was impossible, one could still hope to base the security of quantum bit commitment on a...
