jordan_wigner
(op)[source]¶ Convert a fermionic operator to a qubit operator using the Jordan-Wigner mapping.
For instance, the one-body fermionic operator \(a_2^\dagger a_0\) should be constructed as [2, 0] and the two-body operator \(a_4^\dagger a_3^\dagger a_2 a_1\) should be constructed as [4, 3, 2, 1].
- Parameters
op (list[int]) – the fermionic operator
- Returns
tuple(list[complex], list[list[int, str]]): list of coefficients and the qubit-operator terms
Example
>>> f = [0, 0] >>> q = jordan_wigner(f) >>> q ([(0.5+0j), (-0.5+0j)], [Identity(wires=[0]), PauliZ(wires=[0])]) # corresponds to :math:`\frac{1}{2}(I_0 - Z_0)`
