1306.5357 (Guang Ping He)

Comment on "A short impossibility proof of quantum bit commitment"    [PDF]

Guang Ping He
In a recent letter (Phys. Lett. A 377 (2013) 1076, arXiv:0905.3801), the authors presented an impossibility proof of quantum bit commitment, which attempted to cover all possible protocols that involve both quantum and classical information. Here we show that there are many errors in the proof, thus it fails to exhaust all conceivable protocols.
