The state |G 0 ⟩⟨E 0 n | is randomly chosen for the focused initial condition, based on the algorithm outlined in the previous paragraph. Set the initial electronic condition c G0 = 1 and cE 0 n = 1, based on the focused initial condition, with n 0 = G 0 and ñ0 = E 0 n , and the rest of the coefficients to be zero.
