| 摘 要： | 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。

| Abstract: | 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. |
