On Nondemolition Measurements of Photon Number: A Comment on
quant-ph/0612031
Vladimir S. Mashkevich
abstract: Experimental results stated in quant-ph/0612031 are seminal: The authors have
realized nondemolition measurements of the photon number. As to the
interpretation of the results, it seems to be less than convincing: The
treatment of the system state and of the role of measurement is not compatible
with the conventional point of view. We propose an adequate treatment, in which
the experimental results are a manifestation of a partial Zeno effect (a
slowdown of relaxation).
