RT info:eu-repo/semantics/bachelorThesis T1 Quantum decoherence. A work on the quantum measurement problem A1 Rodr´ıguez Gonz´alez, Sergio AB The objectives of this project are several and their achievement has been organized in three different chapters. In the first one, It has been tried to explain what the measurement problem is andhow decoherence partially solves it, explaining why we are only able to measure non-superposedstates. In the second chapter it is shown how, indeed, decoherence emerges naturally when considering the interaction between a system and its environment, thus giving a justification to VonNeumann’s irreversible reduction process. With these first two chapters, moreover, a mathematical framework based on master equations and CPT maps is established, which is used in thelast chapter to achieve the ultimate goal of being able to describe the evolution of the accessiblestates of a quantum system on which a measurement is performed without having to resort to themeasurement postulates.
