    "abstract": "Mayers, Lo and Chau proved unconditionally secure quantum bit commitment is\nimpossible. It is shown that their proof is valid only for a particular model\nof quantum bit commitment encoding, in general it does not hold good. A\ndifferent model of unconditionally secure quantum bit commitment - both\nentanglement and disentanglement-based - is presented. Even cheating can be\nlegally proved with some legal evidences. Unconditionally secure quantum bit\ncommitment can be established on the top of unconditionally secure quantum coin\ntossing, which is also claimed to be two-way impossible.",
