quantum theory is intrinsically nonlinear, and goes to the standard linear limit for microscopic objects. THe nonlinear theory goes to the classical limit for large objects, but departs from linear quantum mechanics for mesoscopic objects.

Because of the non-linearity, the lifetime of two superposed states is no longer infinite. It decreases as the number of atoms in the object under study increases, going from an astronomically large value for microsystems, to extremely small values for macrosystems. Thus somewhere in between, the superposition lifetime ought to be measureable in the laboratory.

For the micro-mirror of a billion atoms, the superposition lifetime is predicted to be about ten days. If the number of atoms in the mirror is increased a thousand fold, the lifetime of superposition comes down to about a thousand seconds.
