The ensemble interpretation of QM essentially ignores the wave function collapse, and apparently decoherence as well, by stating that only the statistical distributions within ensembles of systems matter (each system being in just one state).

My questions are:

Does the preparation of macroscopic superimposed states (cats) in Bose-Einstein condensates (BEC) effectively negate this interpretation?

As I understand it, the macroscopic superposition of states in a BEC is a single (usually described as a two state) macroscopic quantum system although it may consist of tens of thousands of atoms. Is this correct?
