标题： Jarzynski equality for superconducting optical cavities: an alternative path to determine Helmholtz free energy

摘要： 一种超导腔模型被提出，作为实验研究量子系统中所做的功的一种方法。 我们发现自由能变化与量子腔上下文中可见度测量之间存在简单的数学关系。 如果我们考虑时间$t_0$和$t_\lambda$（协议时间）处的哈密顿量之差作为量子功，那么Jarzynski等式是有效的，且可见度可用于确定作用在腔上的功。 显示英文摘要

摘要： A superconducting cavity model was proposed as a way to experimentally investigate the work performed in a quantum system. We found a simple mathematical relationship between the free energy variation and visibility measurement in quantum cavity context. If we consider the difference of Hamiltonian at time $t_0$ and $t_\lambda$ (protocol time) as a quantum work, then the Jarzynski equality is valid and the visibility can be used to determine the work done on the cavity.
