qiskit.chemistry.components.variational_forms.UVCC.compute_excitation_lists

static UVCC.compute_excitation_lists(basis, degrees)

Compute the list with all possible excitation for given orders

Parameters

• basis (List[int]) – Is a list defining the number of modals per mode. E.g. for a 3 modes system with 4 modals per mode basis = [4,4,4]

• degrees (List[int]) – degree of excitation to be included (for single and double excitations degrees=[0,1])

Return type

List[List[int]]

Returns

List of excitation indexes in terms of modes and modals

Raises

ValueError – If excitation degree is greater than size of basis
