I Has Quantum Mechanics Solved the Measurement Problem?

[entropy1]

Is the measurement problem in QM addressed and solved by now?

If not, can we speak of QM as a description of reality?

Given the statistical nature of QM, can we say it predicts reality?

What is it that QM addresses?

What research have you done on this topic yourself?

What about it didn't you understand?

What research have you done on this topic yourself?

Only Leonard Susskind yet. Maybe I will study more.

What about it didn't you understand?

I am wondering how there can be measurement outcomes if there is no collapse.

You're not helping yourself. You wrote four vague questions ("What is it that QM addresses?" is something textbooks are written on), and when pressed on what you didn't understand, posted a fifth one.

You have to do some work on this.

You have to do some work on this.

So, there is no simple answer. Except for the answer that nobody knows, I understand. (as PF is another source of my information)

I am not sure if I will study QM in depth for I doubt I am able. So it seems I am not qualified to ask the kind of questions I did.

Topic may be closed if no one has any contribution to make to it.

Nope, it is an on-going discussion.

Nope, it is an on-going discussion.

This is from the review article cited below

The dynamics of finite dimensional quantum system, as described in the previous section, is recurrent [99-103] and time reversal invariant. Hence, genuine equilibration in the sense [..] that entropy can only grow over time is impossible.

It makes one wonder why they are still trying to do the impossible. Unitary time-reversible evolution is NOT what is driving the dynamics.

No. As @StevieTNZ said, it's an ongoing area of research.

If not, can we speak of QM as a description of reality?

Given the statistical nature of QM, can we say it predicts reality?

These questions aren't questions about physics, since "reality" is not a physics term, it's a philosophy (or metaphysics, if you like) term. So they're off topic here.

What is it that QM addresses?

This question is way too general for a PF thread.

The OP has been sufficiently addressed. Thread closed.
