    • One can imagine obtaining the state in Eq. 5 by, e.g., transferring an internal excitation from the flying to the target particle or using an auxiliary field that becomes resonant with the target particle only in the presence of the flying particle. Although these processes are challenging for present-day experiments, the important thing to us is that they are consistent with realistic physical processes.

    • It can be shown that Eq. 8 is the optimal state that maximizes the fidelity, regardless of the rotation angle (for a π 2 rotation it gives F=0.819). However, we shall not include the details of the calculation here.
