The original version of this Article contained errors in Figure 2 where the gray data curves were incorrectly captured in panels (a) and (b).

The original Figure 2 and accompanying legend appear below.

Figure 2

Near resonance Rabi oscillations between the two pendula with mean frequency $\omega _0/2\pi \simeq 528$ mHz, frequency difference $\Delta /2\pi =11.7\,$ mHz and modulation frequency $\Omega /2\pi =11.8\,$ mHz. At $t=0$ pendulum 1 was deflected at maximally attracting lower and no upper magnets. Individual oscillations are not visible owing to the time axis covering 45 minutes. (a, b) Deflections $\varphi _1(t)$ and $\varphi _2(t)$ of the two pendula for the pivot distances $L=496.5\,$ mm and $L=330.0\,$ mm resulting in Rabi frequencies of $\Omega _\text{ R }/2\pi =0.47\,$ mHz versus $\Omega _\text{ R }/2\pi =3.69\,$ mHz. (c, d) Effective frequency $\Omega _\text {eff}(\Delta )$ and visibility $\nu (\Delta )$ of the Rabi oscillations for $L=454.0\,$ mm. The solid lines represent model predictions.
