On November 2021 Ms. Andrea Iglesias presented the MSc thesis dissertation Optimization through Quantum Computing to opt for the master's degree in Data Science of the Faculty of Informatics of Barcelona advised by prof. F.-Javier Heredia. This thesis explores the application of quantum computing techniques to solve Quadratic Unconstrained Binary Optimization problems (QUBO), proposing an improved reformulation of the classical multi-period unit commitment problem as a QUBO problem, and then solving the problem with the Quantum Approximate Optimization Algorithm (QAOA).
