Quantum oblivious transfer and bit commitment protocols based on two non-orthogonal states coding

Abstract

Oblivious transfer protocols (R-OT and OT${}_1^2$) are presented based on non-orthogonal states transmission, and the bit commitment protocols on the top of OT${}_1^2$ are constructed. Although these OT protocols are all unconditional secure, the bit commitment protocols based on OT protocols are not secure against attack similar to that presented by no-go theorem.
