我们为反馈控制系统和记录测量结果的存储器导出了积分量子涨落定理和量子Jarzynski等式。得到的等式涉及信息内容，反映了系统与存储器之间的信息交换，并考虑了与经典情况相反的一般测量的反作用。在测量和反馈控制下的热力学第二定律是由这些等式再现的。
We derive integral quantum fluctuation theorems and quantum Jarzynski equalities for a feedback-controlled system and a memory which registers outcomes of the measurement. The obtained equalities involve the information content, which reflects the information exchange between the system and the memory, and take into account the back action of a general measurement contrary to the classical case. The generalized second law of thermodynamics under measurement and feedback control is reproduced from these equalities.
