The goal of this article is to introduce the fundamentals of quantum computing, focusing on a promising quantum algorithm and its application to a financial market problem. More specifically, we discuss the portfolio optimization problem using the Quantum Approximate Optimization Algorithm (QAOA). We not only describe the main concepts involved but also consider simple practical examples, involving financial assets available on the Brazilian stock exchange, with codes, both classic and quantum, freely available as a Jupyter Notebook. We also analyze in details the quality of the combinatorial portfolio optimization solutions through QAOA using SENAI/CIMATEC’s ATOS QLM quantum simulator.Article Criteria for nonclassicality in the prepare-and-measure scenario(Physical Review Research, 2020-10-20) Poderini, Davide; Brito, Samuraí Gomes de Aguiar; Nery, Ranieri Vieira; Sciarrino, Fabio; Araújo, Rafael Chaves SoutoArticle Enhancing entanglement and total correlation dynamics via local unitaries(Physical Review A, 2022-02-22) Varela, Joab Morais; Nery, Ranieri Vieira; Moreno Filho, Marcos George Magalhães; Viana, Alice Caroline de Oliveira; Landi, Gabriel; Araújo, Rafael Chaves SoutoArticle Quantifying quantum causal influences(Physical Review A, 2023-08-28) Hutter, Lucas; Araújo, Rafael Chaves Souto; Nery, Ranieri Vieira; Moreno Filho, Marcos George Magalhães; Brod, Daniel Jost
