Unconditionally Secure Quantum Bit Commitment Really Is Impossible
نویسنده
چکیده
Unconditionally secure quantum bit commitment has been shown to be impossible by Mayers [22] and Lo and Chau [18, 19], but the claim is repeatedly challenged. The bit commitment theorem is reviewed here and the central conceptual point, that an ”Einstein-PodolskyRosen’ attack or cheating strategy can always be applied, is clarified. The question of whether following such a cheating strategy can ever be disadvantageous to the cheater is considered and answered in the negative. PACS numbers: 03.67.-a, 03.67.Dd, 89.70.+c

Unconditionally Secure Quantum Bit Commitment is Simply Possible
Mayers, Lo and Chau proved unconditionally secure quantum bit commitment is impossible. It is shown that their proof is valid only for a particular model of quantum bit commitment encoding, in general it does not hold good. A different model of unconditionally secure quantum bit commitment both entanglement and disentanglement-based is presented. Even cheating can be legally proved with some le...

Recently it has been shown, that unconditionally secure quantum bit commitment schemes are in general impossible. I however argue if we allow that an honest Alice can fail with some small probability then secure protocols might exist. A scheme using quantum envelopes is proposed where the Mayers-Chau-Lo strategy fails.

Bit commitment involves the submission of evidence from one party to another so that the evidence can be used to confirm a later revealed bit value by the first party, while the second party cannot determine the bit value from the evidence alone. It is widely believed that unconditionally secure quantum bit commitment is impossible due to quantum entanglement cheating, which is codified in a ge...

. It was claimed that unconditionally secure quantum bit commitment is impossible due to quantum-computer-assisted-entanglement-attack Recently we have shown that quantum computer-assisted-entanglement-attack can be totally foiled by entanglement and quantum computer. Here we present an alternative un-entanglement based quantum bit commitment scheme. Although the scheme is unconditionally secur...
متن کاملUnconditionally Secure Quantum Bit Commitment
Lo and Chau, and independently Mayers, have shown that all quantum bit commitment schemes proposed to date are insecure: one or both participants can cheat if they have a quantum computer. They claim also to have demonstrated that unconditionally secure quantum bit commitment is impossible. However, their no-go arguments rely on models of quantum cryptographic protocols which are insufficiently...
