Verifiable blind quantum computation over collective-noise

Abstract

Abstract Blind quantum computation(BQC) is a new type of secure quantum computation. In the natural environment, the qubits used in BQC will inevitably be affected by the noise, and the client cannot guarantee the correctness of computational results when the server is dishonest. This paper proposes a verifiable BQC over collective-noise based on quantum error correction to solve these two problems. Furthermore, the proposed protocol needs to expand Alice’s quantum capabilities. The client makes single-qubit measurements on the qubits, encoded and transmitted by the server. As a result, they protect qubits used to compute and utilize single-qubits to verify.
