The notion of the thermodynamic entropy in the context of quantum mechanics is a controversial topic. While there were proposals to refer von Neumann entropy as the thermodynamic entropy, it has it’s own limitations. The observational entropy has been developed as a generalization of Boltzmann entropy, and it is presently one of the most promising candidates to provide a clear and well-deﬁned understanding of the thermodynamic entropy in quantum mechanics. In this work, we study the behaviour…

We study observation entropy (OE) for the Quantum kicked top (QKT) model, whose classical counterpart possesses different phases: regular, mixed, or chaotic, depending on the strength of the kicking…

### Continuity bounds on observational entropy and measured relative entropies

- Computer Science
- 2023

A measurement-independent asymptotic continuity bound is derived on the observational entropy for general POVM measurements, making essential use of its property of bounded concavity and showing that observational entropy is uniformly continuous as a function of the measurement.

The framework of classical observational entropy is developed, which is a mathematically rigorous and precise framework for nonequilibrium thermodynamics, explicitly defined in terms of a set of observables, and the correspondence between classical entropy and quantum entropy becomes surprisingly direct and transparent.

This paper numerically solves for the full quantum behavior of a model system of interacting particles in a one-dimensional lattice, and characterize the fluctuations, finding the maximal, minimal, and typical entropy of each type that the system can eventually attain through its evolution.

This work obtains a formula for the entropy of a pure state as it is measured from thermodynamic experiments, solely from the self-entanglement of the wave function, and finds strong numerical evidence that the two are in agreement for nonintegrable systems.

This work shows that the logarithmic entanglement growth is a universal phenomenon characteristic of the many-body localized phase in any number of spatial dimensions, and reveals a broad hierarchy of dephasing time scales present in such a phase.
