Paper Abstract

We analyze a double-slit experiment when the interfering particle is "mesoscopic" and one endeavors to obtain Weicher Weg information by shining light on it. We derive a compact expression for the visibility of the interference pattern: coherence depends on both the spatial and temporal features of the wave function during its travel to the screen. We set a bound on the temperature of the mesoscopic particle in order that its quantum mechanical coherence be maintained.
