Um estudo sobre estados emaranhados e suas aplicações

Abstract

The main purpose of this work is the scientific dissemination of an important part of the physics that is being developed, as well as the understanding of the differences between mixed and pure entangled states, as well as some of their applications. For this, we made a research using a methodology called “List-Based reearch”, about the topic. As an application of entanglement, we present the singlet state, quantum teleportation, the Bell game as well as some strategies for winning in this game. In order to understand these applications, we need to talk a little bit about defining a particle's collapse, which are and what are Bell’s bas is, local and nonlocal correlations, and entanglement types. After the research, we saw the importance of the study of entanglement and how its applications can help in the scientific and technological development. Entanglement can make the development of quantum cryptography possible, a cryptography that is extremely difficult to break because it is based on the state of a set of particles overlapping entangled states, among other applications.
