Description
We re-analyse the optomechanical interferometer experiment
proposed by Marshall, Simon, Penrose and Bouwmeester with the help of
a recently developed quantum-classical hybrid theory. This leads to an
alternative evaluation of the mirror induced decoherence.
Surprisingly, we nd that it behaves essentially in the same way for
suitable initial conditions and experimentally relevant parameters, no
matter whether the mirror is considered a classical or quantum
mechanical object. We discuss the parameter ranges where this result
holds and possible implications for a test of spontaneous collapse
models, for which this experiment has been designed.
