After several days of thinking and researching, I decided to answer my own question.
N.B. The tensor product symbol are omitted when there is no risk in confusion, especially when the index is different. In symbol,.
Firstly, for case , we only consider qubit , in which . As and act on different qubits,
For the Ising traverse field Hamiltonian, we only consider .
For , it can be evaluated as
We can calculate two-qubit operations independently, such that
Numerically, if you cannot convince yourself,
Now, for a more specific example,
