Bases: qiskit.chemistry.drivers.fermionic_driver.FermionicDriver
Qiskit chemistry driver using the PSI4 program.
Parameters
- config (
Union[str,List[str]]) – A molecular configuration conforming to PSI4 format. - molecule (
Optional[Molecule]) – A driver independent Molecule definition instance may be provided. When a molecule is supplied the config parameter is ignored and the Molecule instance, along with basis and hf_method is used to build a basic config instead. The Molecule object is read when the driver is run and converted to the driver dependent configuration for the computation. This allows, for example, the Molecule geometry to be updated to compute different points. - basis (
str) – Basis set - hf_method (
HFMethodType) – Hartree-Fock Method type
Raises
QiskitChemistryError – Invalid Input
Methods
run
PSI4Driver.run()
