Initial Points (qiskit_nature.second_q.algorithms.initial_points)#

Utility classes that provide initial points to use with specific ansatzes.

For some concrete usage examples refer to the how-to guides on using a UCC-like ansatz with a VQE or on using a UVCC-like ansatz with a VQE.

InitialPoint

The initial point interface.

HFInitialPoint

Compute the Hartree-Fock (HF) initial point.

MP2InitialPoint

Compute the second-order Møller-Plesset perturbation theory (MP2) initial point.

VSCFInitialPoint

Compute the vibrational self-consistent field (VSCF) initial point.
