Circuito fotônico para testes de desigualdades de não-contextualidade via medições sequenciais

Abstract

In this work, we develop the details of experimental proposals for the verification of non-contextual inequalities in qutrits through sequential measurements using photonic circuits as physical platforms for implementing states and observables. Initially, an introduction to the concept of quantum contextuality and the relevance of non-contextuality inequalities was carried out. We explained the details of performing sequential measurements and the reason they were chosen as an experimental method as well as the details of the choice of photonic circuits as an experimental plataform to realize the experiments. Finally, we obtained the photonic circuit designs, and their respective experimental parameters, capable of performing non-contextuality tests through the observation of state-dependent and state-independent non-contextuality inequalities in three-level systems.
