>>11902519There is no consensus on the physical reality of the wavefunction and if it can be considered to collapse. It depends what interpretation of quantum mechanics you use.
I believe people either say all particles have their own wavefunction, or that there's only one single wavefunction in the universe, or that there is no wavefunction.
So, under the Copenhagen interpretation, I believe the answer to your question is yes. Who knows what bearing that may have on actual reality, though.
