In this paper we introduce a definition for conditional energy changes due to general quantum measurements, as the change in the conditional energy evaluated before, and after, the measurement process. By imposing minimal physical requirements on these conditional energies, we show that the most general expression for the conditional energy after the measurement is simply the expected value of the Hamiltonian given the post-measurement state. Conversely, the conditional energy before the…

Classicality of the heat produced by quantum measurements
Quantum measurement is ultimately a physical process, resulting from an interaction between the measured system and a measuring apparatus. Considering the physical process of measurement within a
Driving quantum systems with periodic conditional measurements
We investigate the effect of conditional null measurements on a quantum system and find a rich variety of behaviors. Specifically, quantum dynamics with a time independent H in a finite dimensional
Energy conservation and fluctuation theorem are incompatible for quantum work
Measuring fluctuations of work in coherent quantum systems is notoriously problematic. Aiming to reveal the ultimate source of these problems, we demand of work measurement schemes the sheer minimum
Energy conservation and Jarzynski equality are incompatible for quantum work
Measuring the fluctuations of work in coherent quantum systems is notoriously problematic. Aiming to reveal the ultimate source of these problems, we demand of work measurement schemes the sheer
Self-consistency of the two-point energy measurement protocol
The Two-Point energy Measurement (TPM) protocol defines the work done on a system undergoing unitary evolution as the difference in energy measurement outcomes performed before and after such
Quantum mean-square predictors of work
TLDR
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.
Symmetry Constrained Decoherence of Conditional Expectation Values
Conditional expectation values of quantum mechanical observables reflect unique non-classical correlations, and are generally sensitive to decoherence. We consider the circumstances under which such
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
Thermodynamic length and work optimization for Gaussian quantum states
Constructing optimal thermodynamic processes in quantum systems relies on managing the balance between the average excess work and its stochastic fluctuations. Recently it has been shown that two
Quantum superposition of thermodynamic evolutions with opposing time’s arrows
Microscopic physical laws are time-symmetric, hence, a priori there exists no preferential temporal direction. However, the second law of thermodynamics allows one to associate the “forward” temporal

Improvements do appear, and in particular, a measurement scheme is developed that acts simultaneously on two copies of the state and allows us to describe a whole class of coherent transformations.

This article sets up a new formalism to investigate stochastic thermodynamics in the quantum regime, where stochasticity and irreversibility primarily come from quantum measurement. In the absence of

TLDR
Here it is shown that it is only when a measuring device has access to a zero-temperature reservoir-that is, never-that measurement requires no energy.

We generalize the concept of the weak value of a quantum observable to cover arbitrary real positive operator measures. We show that the definition is operationally meaningful in the sense that it

This Letter identifies the boundaries between what is possible or impossible to measure, i.e., between what the authors can see or not, when energy conservation is at stake.

Quantum open systems evolve according to completely positive, trace preserving maps acting on the density operator, which can equivalently be unraveled in term of so-called quantum trajectories.

This work addresses the controversy in the literature regarding the theoretical consistency of the quantum weak value by providing a more general theoretical framework and giving several examples of how that framework relates to existing experimental and theoretical results.

TLDR
A definition of fluctuating work is proposed that is free of previous drawbacks and that allows the deduction of a generalized work-fluctuation theorem that applies for an arbitrary (out-of-equilibrium) initial state.
