Comment on “Particle path through a nested Mach-Zehnder interferometer”
AbstractGriffiths [Phys. Rev. A 94, 032115 (2016)2469-992610.1103/PhysRevA.94.032115] analyzed, in the framework of a consistent histories interpretation, the controversy regarding the approach to the past of a quantum particle introduced by Vaidman [Phys. Rev. A 87, 052104 (2013)PLRAAN1050-294710.1103/PhysRevA.87.052104]. I argue that Griffith's criticism of my approach using an analysis of experiments with weak probes is unfounded.
