     This method takes a Qibo circuit, converts it to a Quimb tensor network circuit, and evaluates the expectation value
     of a Hamiltonian specified by three lists of strings: operators, sites, and coefficients.
     The expectation value is computed by summing the contributions from each term in the Hamiltonian, where each term's

+    expectation is calculated using Quimb's `local_expectation` function.
     Each operator string must act on all different qubits, i.e., for each term, the corresponding sites tuple must contain unique qubit indices.
     Example: operators_list = ['xyz', 'xyz'], sites_list = [(1,2,3), (1,2,3)], coeffs_list = [1, 2]
