Another simple unconditionally secure quantum bit commitment protocol -- beating entanglement attack with split entangled pair
Horace P. Yuen · arXiv (Cornell University) · 2003
By committing one qubit and opening via submitting the second qubit of an entangled pair sent from the other party, it is shown how a secure bit commitment protocol may be obtained. Such protocols, where further quantum communication is used at opening, represent one of several types of protocols not covered by the well-known ``impossibility proof''.
