  This work describes a series of experiments in IBM's 16-qubit Guadalupe
quantum processor to find the ground state of various lattice systems
implemented in the Qiskit library. We aim to design a Variational Quantum
Eigensolver (QVE) resistant to noise and independent of the number of vertices
in the lattice. Furthermore, we test our solution against two Ising models very
important in the study of critical points and phase transitions of magnetic
systems as well as high-temperature superconductors, and quantum magnetism and
charge density. We provide complete result metrics including final energies,
precision percentages, execution times, angular parameters and source code for
experimentation.
