本文研究了几种超导回路结构在热平衡时是否存在超辐射相变。对于一些配置组成的人工原子，其电路图，但没有指定，和一个LC谐振器或传输线，我们确认SRPT的情况下，在热平衡以下类似的分析，不去定理的原子系统。我们还显示了一些其他的配置，SRPT的情况下，不能确认。
Several superconducting circuit configurations are examined on the existence of superradiant phase transitions (SRPTs) in thermal equilibrium. For some configurations consisting of artificial atoms, whose circuit diagrams are however not specified, and an LC resonator or a transmission line, we confirm the absence of SRPTs in the thermal equilibrium following the similar analysis as the no-go theorem for atomic systems. We also show some other configurations where the absence of SRPTs cannot be confirmed.
