Transmon比特通过电容与一个超导TLR（transmission line resonator）耦合。本文采用Transmon比特与TLR之间有更强的耦合常量，提出了一个在STQ（superconducting transmon qubit）系统中制备四比特纠缠簇态（cluster state）的简单方案。与已有的方案相比，此方案有更长的消相干时间。又由于Transmon比特和TLR有以上的属性，此方案在实验上更可行。

Transmon qubits capacitively coupled to a superconducting transmission line resonator (TLR). We adopt transmon qubits which have much stronger coupling constant with TLR and propose a simple scheme to prepare a four-qubit entangled cluster state in superconducting transmon qubit (STQ) system. Compared with the scheme firstly introduced by Zheng Xiao-Juan et al, our schemes have longer dephasing time. Based on the favorable properties of transmons and TLR, our method is more feasible in experiment.
