Delegated Preparation of Quantum Error Correction Code for Blind Quantum Computation

Abstract

The universal blind quantum computation protocol allows a client to delegate quantum computation to a remote server, and keep information private. Since the qubit errors are inevitable in any physical implementation, quantum error correction codes are needed for fault-tolerant blind quantum computation. In this paper, a quantum error correction code preparation protocol is proposed based on remote blind qubit state preparation (RBSP). The code is encoded on the brickwork state for fault-tolerant blind quantum computation. The protocol only requires client emitting weak coherent pulses, which frees client from dependence on quantum memory and quantum computing.
