Teorı́a cuántica, introducción y análisis de su coherencia lógica a la luz de un resultado de Frauchiger y Renner

Abstract

[en] This paper consists of an introduction to quantum theory for finite dimensional systems, mostly 1/2 spin systems. Subsequently, the article “Quantum theory cannot consistently describe the use of itself” is analized, including the result that the authors arrive at: quantum theory is not consistent for complex macroscopic systems. This has generated a lot of controversy, which is why various articles have arisen both in favor and against it, some of them include [3, 4] defending it or [5, 6] criticizing it that I have read in order to understand better the initial article and its arguments. In addition to this, an observation is also made about the proof in [2].
