Uma análise do caráter abstrato da descrição do spin de uma partícula no espaço de estado e suas aplicações aos indicadores de saúde

Abstract

The research that follows explores the abstract character of the description of the spin of a particle, through Paul A. Dirac’s formalism, in state space and seeks to portray its applicability to non-physical systems through the analysis of the qubit description. That said, the work aims to develop a possible application of formalism to health indicators for smokers in Brazil. With this objective, we use the state of superposition of spin states and the qubit formulation and apply them, with due analogies to factors in life that can equally be analyzed as a superposition of states. Firstly, we will explore how the system could be developed and then the system’s applicability in studying the incidence, mortality and prevalence of smoking-related diseases will be demonstrated. Through the probabilistic interpretation of the state vector for the spin and through the necessary abstractions, we construct state ket’s for the health indicators. And relating them to data that presents the number of cases of diseases and deaths linked to smoking in Brazil in 2020, a method is obtained that probabilistically describes the accessible states that lead an individual or a population to death as a result of different diseases. Finally, achieving an estimate of the country’s smoking population in 2020 as a result of the research.
