Curs: 2021-2022. Tutor: Antonio Acín, co-tutors: Korbinian Kottmann, Paolo StornatiWe are setting up a pipeline to simulate variational quantum algorithms for relevant system sizes. Most simulators only allow for a few qubits. With tensor networks we can access much larger systems. One of the most promising algorithms is the variational quantum eigensolver, where a parametrized circuit is optimized to prepare an approximation of the ground state. We are investigating the reverse process of disentangling a ground state to a product state variationally, so we can study the necessary circuit depth needed in order to achieve the disentangling28 p.application/pdfengcc-by-nc-nd (c) Recio, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Algorisme quànticXarxes tensorialsSolucionador quàntic variacionalTreballs de fi de màsterQuantum algorithmTensor networkVariational quantum eigensolverMaster's thesesinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
