Title: Unconditionally Secure Quantum Bit Commitment Is Possible
Authors: Horace P. Yuen
Comments: 12 pages
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. An unconditionally secure bit
commitment protocol utilizing quantum states is presented. A proper
formulation brings out the general condition for successful cheating.
Problems in previous proofs on the general impossibility of quantum
bit commitment are indicated. (10kb)
