Blind Quantum Computation without Trusted Center

TL;DR

This paper introduces two blind quantum computation protocols enabling clients with minimal quantum capabilities to delegate quantum tasks securely without trusted centers, using simple photon operations.

Contribution

The paper presents novel BQC protocols that require clients only to perform rotations or reordering on photons, reducing quantum capability requirements.

Findings

Protocols enable secure quantum delegation with minimal client quantum ability

Clients only need to perform rotations or reordering on received photons

Protocols eliminate the need for trusted centers in BQC

Abstract

Blind quantum computation (BQC) protocol allows a client having partially quantum ability to del- egate his quantum computation to a remote quantum server without leaking any information about the input, the output and the intended computation. Recently, many BQC protocols have been proposed with the intention to make the ability of client more classical. In this paper, we propose two BQC protocols, in which the client does not have to generate photons, but only has to perform either rotation or reorder on the received photons.
