  The apparent random outcome of a quantum measurement is conjectured to be
fundamentally determined by the microscopic state of the macroscopic
measurement apparatus. The apparatus state thus plays the role of a hidden
variable which, in contrast with variables characterizing the measured
microscopic system, is shown to lead to a violation of Bell's inequalities and
to agree with standard quantum mechanics. An explicit realization of this
interpretation is proposed for a primitive model of measurement apparatus
inspired by Mott: in the case of an alpha-particle spherical-wave detection in
a cloud chamber, the direction of the observed linear track is conjectured to
be determined by the position of the atoms of the gas filling the chamber.
Using a stationary-state coupled-channel Born expansion, a reduction of the
spherical wave function is shown to be necessary to compensate the flux loss
due to scattering on the chamber atoms. Being highly non local, this
interpretation of quantum mechanics is finally argued to open the way to
faster-than-light information transfer.
