Three-party d-level quantum secret sharing protocol

TL;DR

This paper introduces a three-party quantum secret sharing protocol using arbitrary dimensional quantum states, allowing the sender to control the state locally and securely share secrets without resource waste.

Contribution

It presents a novel protocol that enhances control and security in quantum secret sharing by eliminating resource waste and preventing premature information leakage.

Findings

The protocol enables local control of quantum states by the sender.

It prevents information leakage to dishonest parties until the final steps.

The method is applicable to arbitrary dimensional quantum states.

Abstract

We develop a three-party quantum secret sharing protocol based on arbitrary dimensional quantum states. In contrast to the previous quantum secret sharing protocols, the sender can always control the state, just using local operations, for adjusting the correlation of measurement directions of three parties and thus there is no waste of resource due to the discord between the directions. Moreover, our protocol contains the hidden value which enables the sender to leak no information of secret key to the dishonest receiver until the last steps of the procedure.
