Microscopic and Macroscopic Interpretations of the Entropy Within the Framework of Quantum Mechanics

Abstract

The objective of this work was to microscopically and macroscopically interpret entropy within the framework of quantum mechanics: quantum computer, Coulomb crystal, chaos, and cosmology. Indeed, in quantum physics, the concept of information is the very basis of the minimal interpretation of the concept of state vector as a contextual prediction tool. The Coulomb crystal is the basic element for the development of a quantum computer. For example, the Coulomb crystal represents the basic element of high precision clocks, provides a favorable environment for the detailed study of chemical reactions, and constitutes an original technology for the development of a quantum computer. In addition, the combination of chaos with the recent definition of entropy allows us to understand very small systems at the atomic and quantum microscopic level, as well as very large systems at the macroscopic level of galaxies and black holes.
