In open quantum systems, a clear distinction between work and heat is often challenging, and extending the quantum Jarzynski equality to systems evolving under general quantum channels beyond unitality remains an open problem in quantum thermodynamics. In this Letter, we introduce well-defined notions of guessed quantum heat and guessed quantum work, by exploiting the one-time measurement scheme, which only requires an initial energy measurement on the system alone. We derive a modified quantum… 
Work Measurement in OPEN Quantum System
Work is an important quantity in thermodynamics. In a closed quanutm system, the two-point energy measurements can be applied to measure the work but cannot be utilized in an open quantum system.
Kirkwood-Dirac quasiprobability approach to quantum fluctuations: Theoretical and experimental perspectives
Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability (KDQ) as a tool to encapsulate non-classical features in the context of condensed matter physics (scram-bling,
Quasiprobability fluctuation theorem behind the spread of quantum information
Information spreads in time evolution. For example, the quantum correlation decays when the correlated system locally couples to a third party, such as the environment. This simple but important fact

Quantum Heat Engines with Complex Working Media, Complete Otto Cycles and Heuristics
This paper examines the performance of a quasi-static quantum Otto engine based on two spins of arbitrary magnitudes subject to an external magnetic field and coupled via an isotropic Heisenberg exchange interaction and formulates heuristics to infer the necessary conditions for an engine with uncoupled as well as coupled spin model.
Quantum mean-square predictors of work
This letter casts the determination of the work distribution as a problem in statistical inference, which can be directly connected to experimental methods, as it is illustrated by considering a qubit subject to an avoided crossing work protocol.
Quantum and Classical Ergotropy from Relative Entropies
The classical ergotropy is defined, which quantifies how much work can be extracted from distributions that are inhomogeneous on the energy surfaces, which is provided by geometric quantum mechanics, for which the geometric relative entropy is defined.
Thermalization processes induced by quantum monitoring in multilevel systems.
The heat statistics of a multilevel N-dimensional quantum system monitored by a sequence of projective measurements are studied and it is shown that ITT is identified by the fixed point of a symmetric random matrix that models the stochastic process originated by the sequence of measurements.

Quantum work statistics close to equilibrium
We study the statistics of work, dissipation, and entropy production of a quantum quasi-isothermal process, where the system remains close to the thermal equilibrium along the transformation. We
Quantum Fluctuation Theorems beyond Two-Point Measurements.
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

Experimental test of exchange fluctuation relations in an open quantum system
Elucidating the energy transfer between a quantum system and a reservoir is a central issue in quantum non-equilibrium thermodynamics, which could provide novel tools to engineer quantum-enhanced
Energetic footprints of irreversibility in the quantum regime
In classical thermodynamic processes the unavoidable presence of irreversibility, quantified by the entropy production, carries two energetic footprints: the reduction of extractable work from the
