qiskit.chemistry.drivers.FermionicDriver

class FermionicDriver(molecule=None, basis='sto3g', hf_method='rhf', supports_molecule=False)

Base class for Qiskit’s chemistry fermionic drivers.

Parameters

• molecule (Optional[Molecule]) – molecule

• basis (str) – basis set

• hf_method (str) – Hartree-Fock Method type

• supports_molecule (bool) – Indicates if driver supports molecule

Raises

QiskitChemistryError – Molecule passed but driver doesn’t support it.

abstract __init__(molecule=None, basis='sto3g', hf_method='rhf', supports_molecule=False)

Parameters
