Fig. 4 — a We orient an ion pair along the x axis with a separation of about 5 μm (read from the image on the CCD camera as 0.88 μm/pixel). Then we push the ion pair away from the micromotion-free z axis by a bias electric field. The relative micromotion amplitudes of the two ions are indicated by the blue arrows, which are not to scale with the ion spacing or their displacements. b Rabi oscillations of the lower ion under a Raman laser with the same intensity before (blue) and after (orange) the displacement. c Theoretical relative Rabi rate r vs. the micromotion amplitude A in the unit of the laser waist radius R = 1.5 μm. d Bell-state fidelity vs. the number of entangling gates for the ion pairs before (blue) and after (orange) the displacement. We fit both gate infidelities to be 1.7(1)%. All the error bars represent one standard deviation.
