A simple practical quantum bit commitment protocol

TL;DR

This paper introduces a straightforward quantum bit commitment protocol that balances ease of implementation with enhanced security, approaching unconditional security without being perfectly binding or concealing.

Contribution

The paper presents a simple, practical quantum bit commitment protocol that improves security while maintaining ease of implementation.

Findings

Protocol is as easy to implement as existing methods

Achieves near-unconditional security

Not perfectly binding or concealing

Abstract

This paper devises a simple quantum bit commitment protocol that is just as easy to implement as any existing practical quantum bit commitment protocols but will be more secure. It will be infinitely close to being unconditionally fully secure although neither perfectly binding nor perfectly concealing.
