Project Description:

To calculate the ground state energy of the given Hamiltonian, we use the fine tuned ADAPT-VQE algorithm with qubit pool generated from fermion creation and annihilation operators and HF initial state. In each iteration, Adam optimizer is used to find a local best parameter series. Sampling estimator is used to calculate the expectation value of energy and operator gradient.
