Abstract A representation of the Ising model in a longitudinal magnetic field on a quantum computer is introduced. The ansatz of the wave function of the model for a quantum approximation optimization algorithm is constructed. The scheme and the result of its operation for a lattice of size 2 × 2 are presented.
