“…According to RBSP with two decoy states, data pulses are used to prepare the required data qubits {|+ θi } S 1 , and each data qubit is encoded into a required logical qubit. Hence, the number of data pulses is equal to RBSP with two decoy states, denoted as N d [12]. The number of ancilla pulses depends on the encoding circuit on cluster state, as shown in Fig.…”

“…[5][6][7]. In recent years, many extension BQC protocols have sprung up like mushrooms after the rain [8][9][10][11][12][13][14]. The Universal Blind Quantum Computation(UBQC) proposed by Broadbent, Fitzsimons, and Kashefi [7] stands as one of the typical protocols, which only requires Alice to prepare the single photon states.…”

“…On this basis, the multi-decoy states technique in quantum key distribution [15] can also be applied to UBQC protocol. Afterward, Zhao and Li proposed a blind quantum state preparation protocol with two decoy states [10][11][12], which further improves the preparation efficiency. Their simulation experiments also show that the preparation protocol with two decoy states is more suitable for long-distance communication.…”

The Blind Quantum Computation (BQC) protocol allows for privacypreserving remote quantum computations. In this paper, we introduce a remote quantum error correction code preparation protocol for BQC using a cluster state and analyze its -blindness in the measurement-based quantum computation model. Our protocol requires fewer quantum resources than previous methods, as it only needs weak coherent pulses, eliminating the need for quantum memory and limited quantum computing. The results of our theoretical analysis and simulations show that our protocol requires fewer quantum resources compared to non-coding methods with the same success rate.

“…One possible solution to address this problem is via the Blind Quantum Computation (BQC) protocol supported by quantum cloud computing, which enables a client(say Alice) with limited quantum technology to delegate a computing task to a remote quantum server(say Bob) while ensuring computing information privacy [1], [2], [3]. In recent years, a number of BQC protocols have been proposed [4], [5], [6], [7], [8], [9]. Among these protocols, Universal Blind Quantum Computation (UBQC) is of particular interest as it not only can guarantee that Alice's inputs, outputs and quantum algorithms are unknown to server while delegating computation, but also only requires Alice to prepare the single photon states.…”

“…After then, it has been also experimentally demonstrated. Based on UBQC [17], some other measurement-based BQC protocols [7], [18], [19], [20], [21], [22] have been devised to be as practical as possible in recent years. To verify the blindness and correctness of practical BQC, some protocols [18], [19] were also proposed in noisy channels or existing any malicious attacker.…”

The Blind Quantum Computation (BQC) is a delegated protocol, which allows a client to rent a remote quantum server to implement desired quantum computations, while keeping her inputs, outputs and algorithms privacy. However, the qubit errors during the quantum computation are realistic issues that are needed to consider. In this paper, we propose a fault-tolerant blind quantum computation protocol with quantum error-correcting codes to avoid the accumulation and propagation of qubit errors during the computing. Meanwhile, we also present the -blindness in our protocol. To improve the error correction performance, the concatenated codes are used in our protocol. We further present the resources consumption of photon pulses by the optimal level concatenation codes. The simulation results show that our scheme not only can improve the preparation efficiency but also reduce quantum resources, which shows a significant improvement to a realistic faulttolerant BQC.
