replying to: H. F. Legg. Nature https://doi.org/10.1038/s41586-026-10567-8 (2026).<br>In our previous study1, we reported single-shot parity readout in an InAs–Al hybrid nanowire device, evidenced by an h/2e-flux-periodic random telegraph signal (RTS) in the quantum capacitance (CQ). These radio frequency (RF) interferometric measurements strongly indicate a topological origin: they are consistent with our theoretical model and very strongly constrain non-topological explanations. In the accompanying Comment2, Legg claimed that our transport data points to a gapless state. However, our analysis of our CQ measurements does not assume the existence of a gap. Indeed, a gapless system would not exhibit a stable h/2e-periodic bimodal signal: the interferometric contrast would wash out due to collapse of the oscillation amplitude or time scales.
