    • We can also envisage a superexchange mechanism to obtain a Heisenberg interaction by using three aligned quantum dots where the middle one has a higher-energy level (by the amount (Formula presented) such that the electron spins of the outer two dots are also Heisenberg coupled, but now with the exchange coupling being (Formula presented)

    • We note that explicitly (Formula presented) with the corresponding XOR Hamiltonian (Formula presented) (Formula presented). An alternative way to achieve the XOR operation is given by (Formula presented). This form has the potential advantage that the single-qubit operations involve only spin 1
