openfermion.testing.random_quadratic_hamiltonian

Generate a random instance of QuadraticHamiltonian.

openfermion.testing.random_quadratic_hamiltonian(
    n_orbitals,
    conserves_particle_number=False,
    real=False,
    expand_spin=False,
    seed=None
)

Used in the notebooks

Used in the tutorials

n_orbitals int

the number of orbitals

conserves_particle_number bool

whether the returned Hamiltonian should conserve particle number

real bool

whether to use only real numbers

expand_spin Whether to expand each orbital symmetrically into two spin orbitals. Note that if this option is set to True, then the total number of orbitals will be doubled.
