Publicly Verifiable Blind Quantum Computation

TL;DR

This paper introduces a new blind quantum computation protocol that allows any third party to verify the correctness of the computation, enhancing trust and security in delegated quantum tasks.

Contribution

It proposes a novel blind quantum computation protocol with public verifiability, enabling third-party verification of the computation's integrity.

Findings

Enables third-party verification of quantum computations.

Maintains user privacy while allowing public verification.

Strengthens security against dishonest participants.

Abstract

Blind quantum computation protocols allow a user with limited quantum technology to delegate an intractable computation to a quantum server while keeping the computation perfectly secret. Whereas in some protocols a user can verify that calculated outcomes are correct, a third party cannot do this, which allows a dishonest user or owner to benefit illegally. I propose a new blind quantum computation protocol with a new property called public verifiability, which enables any third party to assure that a party does not benefit from attempted deception.
