Sample a random UCCSD operator.

Parameters:

norb (int) – The number of spatial orbitals.
nocc (int) – The number of spatial orbitals that are occupied by electrons.
with_final_orbital_rotation (bool) – Whether to include a final orbital rotation in the operator.
seed – A seed to initialize the pseudorandom number generator. Should be a valid input to np.random.default_rng.

Return type:

UCCSDOpRestricted

Returns:

The sampled UCCSD operator.
