Cover Story: State changes of systems due to interventions of "intelligent beings'' that can lead to a decrease in entropy are widely discussed in the literature. We propose here to take them as examples of "conditional actions'' and to describe them mathematically as "instruments'' following the quantum theory of measurement. As a detailed case study, we calculate the imperfect erasure of a qubit, which can also be considered as a conditional action and is realized by coupling a spin to another small spin system in its ground state. This analysis casts a critical light on the widely accepted LandauerBennett principle. From our point of view, erasing memory content appears as an additional conditional action, but it is neither necessary nor sufficient to solve Maxwell's demon paradox. View this paper

  • Sandro Gallo

23 March 2021

From a physical/dynamical system perspective, the potential well represents the proportional mass of points that escape the neighbourhood of a given point. In the last 20 years, several works have shown the importance of this quantity to obtain preci...

  • Markus Zanker

23 March 2021

The Multi-Armed Bandit (MAB) problem has been extensively studied in order to address real-world challenges related to sequential decision making. In this setting, an agent selects the best action to be performed at time-step t, based on the past rew...
