Abstract
We present a new simulation-secure quantum oblivious transfer (QOT) protocol based on one-way functions in the plain model. With a focus on practical implementation, our protocol surpasses prior works in efficiency, promising feasible experimental realization. We address potential experimental errors and their correction, offering analytical expressions to facilitate the analysis of the required quantum resources. Technically, we achieve simulation security for QOT through an equivocal and relaxed-extractable quantum bit commitment.
Overview
This article presents a simulation-secure quantum oblivious-transfer protocol from one-way functions in the plain model, with explicit attention to efficiency, experimental errors, and the required quantum resources.
