Circuit growth and subspace read-out in quantum-selected configuration interaction: Separating the Hartree-Fock determinant

Predicting many molecular properties requires accurate ground-state energies of molecular Hamiltonians. Quantum-selected configuration interaction (QSCI) obtains such energies by measuring an input state to select important electronic configurations and classically diagonalizing the Hamiltonian in the subspace they spa...
