  The test of modifications to quantum mechanics aimed at identifying the
fundamental reasons behind the un-observability of quantum mechanical
superpositions at the macro-scale is a crucial goal of modern quantum
mechanics. Within the context of collapse models, current proposals based on
interferometric techniques for their falsification are far from the
experimental state-of-the-art. Here we discuss an alternative approach to the
testing of quantum collapse models that, by bypassing the need for the
preparation of quantum superposition states might help us addressing non-linear
stochastic mechanisms such as the one at the basis of the continuous
spontaneous localisation model.
