A system-only two-point measurement framework delivers exact fluctuation relations for work and heat in open quantum systems along with Jarzynski corrections, recovering prior results for closed systems and holding exactly for pure decoherence.
Namely, we search for an operatorOw(t)such that ⟨Ow(t)⟩t−⟨Ow(0)⟩0 =δWS(t),(32) where, compared with Eq.(7), we introduced the nota- tion⟨O⟩t = Tr{OρS(t)}

Fluctuations of path-dependent thermodynamic quantities in open quantum systems via two-point system-only measurements
A system-only two-point measurement framework delivers exact fluctuation relations for work and heat in open quantum systems along with Jarzynski corrections, recovering prior results for closed systems and holding exactly for pure decoherence.
