RT info:eu-repo/semantics/bachelorThesis T1 Entanglement, decoherence and the transition from quantum to classical. A1 Mora Herrera, Elisa A2 Grado En Física AB In this work we present the behaviour of open quantum systems, as they getentangled with their environment and the decoherence process that it leads. Thisis, in fact, the transition to quantum to classical world, the lost of information inthis process and how long it takes are the principal topics we study in this lines.We will make a educational review of an article in modern research in quantumphysics “Entanglement of quantum clocks through gravity” (Ruiz et al., 2017),where quantum clocks located in nearby worldlines get entangled through thegravitational interaction, leading to a loss of coherence of a single clock and anuncertainty in the time measuring process YR 2022 FD 2022 LK http://riull.ull.es/xmlui/handle/915/28454 UL http://riull.ull.es/xmlui/handle/915/28454 LA es DS Repositorio institucional de la Universidad de La Laguna RD 14-jun-2024
