The problem of finding the lowest-energy state in the Ising model with a longitudinal magnetic fieldis studied for two- and three-dimensional lattices of various sizes using the Quantum Approximate Optimiza-tion Algorithm (QAOA). The basis states of the quantum computer register correspond to spin configurationson a spatial lattice, and the Hamiltonian of the model is implemented using a sequence of quantum gates. Theaverage energy value is efficiently measured using the Hadamard test. We simulate the QAOA operation onincreasingly complex lattice configurations using the software librariesCirqandqsim. The results of optimiza-tion, obtained using gradient-based and gradient-free methods, demonstrate the superiority of the latter in bothmodeling performance and quantum computer usage. Key arguments in favor of the advantages of quantumcomputation for this problem are presented
