Quantum fluctuation theorems beyond two-point measurements

26 Sep 2019 · Micadei Kaonan, Landi Gabriel T., Lutz Eric ·

We derive detailed and integral quantum fluctuation theorems for heat exchange in a quantum correlated bipartite thermal system using the framework of dynamic Bayesian networks. Contrary to the usual two-projective-measurement scheme that is known to destroy quantum features, these fluctuation relations fully capture quantum correlations and quantum coherence at arbitrary times.
