Unconditionally Secure Quantum Bit Commitment Protocols Based on Correlation Immune Boolean Function

Quantum Physics 2007-05-23 v6

Abstract

A class of quantum protocols of bit commitment is constructed based on the nonorthogonal states coding and the correlation immunity of some Boolean functions. The binding condition of these protocols is guaranteed mainly by the law of causality and the concealing condition is guaranteed by the indistinguishability between nonorthogonal quantum states and the correlation immunity of Boolean functions. We also give out an oblivious transfer protocol based on two-nonorthogonal states coding and build a bit commitment protocol on top of it. The relationship between these protocols and the well known no-go theorem is also discussed in details.
