In the original manuscript, a residual RMS timing jitter below 2 fs between pump and seed pulses in the stabilized case was claimed. Following a reevaluation of the data, this was underestimated. Due to a rounding error in the calibration routine, a miscalculated calibration factor was extracted. By using a higher precision, the updated residual timing jitter amounts to 2.76 fs, or sub-3 fs. In this erratum, the calibration routine is briefly reviewed and Fig. 4, which presents the timing jitter in the stabilized and unstabilized case, is updated. All other results remain unaffected.

(a) Short-term timing jitter unsynchronized (blue) and with active synchronization (green). The RMS timing jitter in the stabilized case is reduced to σ < 3 fs. The inset shows a histogram of the measured timing jitter values. (b) Long-term measurement of the timing delay between the pump and seed pulses. Inset: Activation of the stabilization after 2 min.
