Webric as in the case of the coordinate representation, which entails operations with complex numbers that cause an additional burden on a computational system. Figure1 shows the dependence of the program execution time, t1,onthe dimension of the density matrix dim[ρ] in two different representations of the Hamiltonian. WebThe Hamiltonian is represented as a linear combination of other operators, e.g., ∑N −1 k=0 ckOk ∑ k = 0 N − 1 c k O k, where the ck c k are trainable parameters.
