Unconditionally Secure Quantum Bit Commitment
Horace P. Yuen · arXiv (Cornell University) · 2005
The ``impossibility proof'' on unconditionally secure quantum bit commitment is examined. It is shown that the possibility of juxtaposing quantum and classical randomness has not been properly taken into account. A specific protocol that beats entanglement cheating with entanglement is proven to be unconditionally secure.
