Perhaps we discuss the idea of, 'plurality of of objects" in relation to the wave function. I am of course assuming this is what you are alluding to.
I wanted to contrast a plurality of objective states, against a complete lack of objective states. It is not how the solipsists suggest it is -- (they would say non-existence of states outside of the human mind). QM apparently suggests that the material world will occupy "all states" until measured.
Secondly, trees falling in a forest when there is no one around to hear them fall ( as per Berkeley) is not really about a dichotomy in terms of making a sound or not making a sound. What it actually refers to is the idea of EXPERIENCED sound. If there is no one to hear a tree fall then there is no first person EXPERIENCE of the sound.
The entangled photon experiment is the same situation, except replace the word 'EXPERIENCED' with 'MEASURED.'
Firstly,I don't think we can describe entanglement and/or superposition as existing in some type of multiple objective states at once; whereby the observer forced one objective state to be realized. It would be a bit like saying that Schrodinger's cat exists in terms of one live cat and one dead cat, or the one cat exists as both a live cat and a dead cat. When we observe the cat(s) we just see one cat in a particular state of health. Something similar to this is possible in the many words interpretation of quantum mechanics.
Secondly, I don't think the superposition analogy words for the fallen tree idea. It is a bit like the cat in a box. An unobserved tree that has fallen has both created a noise and hasn't created a noise. I would say that "experienced" noise in this case is not a quantum explanation. The tree actually makes a noise when it falls it is just that there is no one around to experience the sound.
I think you are going to have problems with "plurality of objects" in terms of quantum mechanics.But anyway, over to you.
Sorry, I forgot to replace "experienced" with "measured"
