Integral Quantum Fluctuation Theorems under Measurement and Feedback control

Statistical Mechanics 2014-01-30 v3 Quantum Physics

Abstract

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 are reproduced from these equalities.
