Reply to “Comment on ‘Reduced coherence in double-slit diffraction of neutrons’ ”

We reply to the comment by Sanz and Borondo [Phys. Rev. A 77, 057601 (2008)] on our paper [Tumulka et al., Phys. Rev. A 75, 055602 (2007)] concerning the double-slit diffraction experiment with neutrons published in Zeilinger et al. [Rev. Mod. Phys. 60, 1067 (1988)]. We argue in particular that Sanz and Borondo’s new arguments for the presence of significant decoherence in that experiment are unconvincing.
