qrunch.chemistry.ground_state_problem.calculators.tools.initial_ansatz.initial_ansatz_protocols

Interface for defining an initial wave-function ansatz (Usually a Hartree-Fock state) for a molecule.

An initial ansatz can create an initial quantum circuit that represents initial wave-function ansatz. The initial quantum circuit can then be provided to a basic VQE and an Adaptive VQE.
