在电路量子电动力学系统中，本文提出利用磁通比特和 LC 电路间的耦合来制备多比特的一维cluster态的方案。方案中，LC电路作为中间转化器，通过选择恰当电磁场的参数和调节比特间的能级间隔，使磁通比特间发生纠缠从而制备出多比特的一维cluster态。在大失谐的条件下，磁通比特和量子数据总线间的相互作用可通过调节虚光子来转化。此外，该方案的合理性也已在实验上得到了证明。

We proposed a scheme in the paper to produce multi-qubit one-dimensional cluster state via coupling flux qubits to LC circuit in circuit quantum electrodynamics (QED) system .The LC circuit acted as a quantum data bus (QDB) .The multi-qubit one-dimensional cluster state was produced by choosing appropriate parameters for the time-dependent electromagnetic field (TDEF ) and adjusting the level spacing of the qubits .With the large detuning ,the interaction between the qubits and the QDB can be adjusted via the exchange of virtual rather than real photons .Moreover ,the experimental feasibility of the scheme was also shown .
