Quantum computing has considerable advantages in solving some problems overits classical counterpart. Currently various physical systems are developed toconstruct quantum computers but it is still challenging and the first use ofquantum computers may adopt the cloud style. Blind quantum computing (BQC)provides a solution for clients with limited quantum capabilities to delegatetheir quantum computation to remote quantum servers while keeping input,output, and even algorithm private. In this paper, we propose three multi-partyverifiable blind quantum computing (VBQC) protocols with identityauthentication to handle clients with varying quantum capabilities in quantumnetworks, such as those who can just make measurements, prepare single qubits,or perform a few single-qubit gates. They are client-friendly and flexiblesince the clients can achieve BQC depending on their own quantum devices andresist both insider outsider attacks in quantum networks. Furthermore, all thethree proposed protocols are verifiable, namely that the clients can verify thecorrectness of their calculations.
