  A theoretical prediction published in Phys.Rev. B 64, 012505 (2001) is
corroborated experimentally. This corroboration of the theoretical result
published in Physical Review B was rejected for publication in the same
journal. Such inconsistency is connected with a contradiction to the second law
of thermodynamics. According to the theory Phys.Rev. B 64, 012505 (2001) the
energy of a noise can be transformed to a dc power in superconducting loop and
therefore a dc voltage oscillating with magnetic field can be observed on
segments of an inhomogeneous loop in the temperature region close to the
superconducting transition. Such quantum voltage oscillations observed in the
present work can be induced both by an external electrical noise and by
internal equilibrium noise (thermal fluctuations). Violation of the second law
takes place in the second case. First of all the theoretical result published
by Phys.Rev.B is challenge to the second law but about this contradiction was
openly written only in the first version (see physics/0105059) of the
experimental paper rejected by Referees of Phys.Rev.B. The transformation of an
external electrical noise to the dc voltage was confirmed recently in the paper
published in JETP Letters 77, 371 (2003) (see also cond-mat/0303538).
