Wave-function collapse induced by thermal fluctuations of detector variables. statistical collapse of wave functions

  • Tsunehiro Kobayashi


We present a simple example where the wave-function collapse is realized by thermal fluctuations of detector variables. This mechanism for the wave-function collapse is essentially due to the indeterminacy of the initial internal-states of detectors by the thermal fluctuation. Two types of the collapse are shown: One is the mechanism of the collapse arising from the phase ambiguity of the initial detector state and another is that derived from the fluctuation of the number of particles in the detector actively working in single measurement process.
