“…Blind quantum computing (BQC) was first proposed by Childs [103], his demand was that a user (client) with limited amount of quantum resources may delegate a task to another user or quantum server having full quantum capability or more quantum power, with the condition that input and output of the client and the computational task performed are kept in private, i.e., the server or the user with higher quantum power remains blind about these information. Several schemes of BQC with identity authentication have been proposed [104][105][106], but the capability for BQC in designing schemes of QIA is not yet fully utilized. However, in Ref.…”

Secure communication has achieved a new dimension with the advent of the schemes of quantum key distribution (QKD) as in contrast to classical cryptography, quantum cryptography can provide unconditional security. However, a successful implementation of a scheme of QKD requires identity authentication as a prerequisite. A security loophole in the identity authentication scheme may lead to the vulnerability of the entire secure communication scheme. Consequently, identity authentication is extremely important and in the last three decades several schemes for identity authentication, using quantum resources have been proposed. The chronological development of these protocols, which are now referred to as quantum identity authentication (QIA) protocols, are briefly reviewed here with specific attention to the causal connection involved in their development. The existing protocols are classified on the basis of the required quantum resources and their relative merits and demerits are analyzed. Further, in the process of the classification of the protocols for QIA, it's observed that the existing protocols can also be classified in a few groups based on the [inherent computational tasks used to design the protocols. Realization of these symmetries has led to the possibility of designing a set of new protocols for quantum identity authentication, which are based on the existing schemes of the secure computational and communication tasks. The security of such protocols is also critically analyzed.

“…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.

“…However, the client cannot check correctness of the results in these BQC protocols. Terefore, various verifable BQC protocols have been proposed [19][20][21][22][23][24][25][26]. For example, Fitzsimons and Kashef proposed a universal verifable BQC protocol, called the FK protocol, where the client can detect any malicious behavior of the server with high probability by using trap qubits [19].…”

Multiparty delegated quantum computation (MDQC) allows multiple clients with limited quantum capability to jointly complete a quantum computational task with the aid of an untrusted quantum server. But in existing MDQC protocols, the verifiability that clients should verify whether the server executed the protocol correctly and gave correct results was not handled. Therefore, in this paper, we improve a typical MDQC protocol to enable clients to verify the correctness of computation by inserting trap qubits and develop a novel method to enforce clients to send qubits honestly while avoiding the positions of trap qubits being leaked to the server. The security and verifiability of the improved MDQC protocol are also analyzed. In addition, a specific example of the proposed verifiable MDQC protocol is given and simulated on IBM’s quantum platform.
