Question

Will quantum mechanics every be deterministic in the future when we get better grasp of it?

Answer 1

This is an excellent question.  There is no answer...yet...because so many things are uncertain (pun intended) about the future.

The Heisenberg Uncertainty Principle say no...that location and momentum are and will remain uncertain in quanta.  So we can only use probabilities to describe these characteristics in quanta.

But you know, as we are able to generate higher and higher energies and, therefore, more and more precise observations, who knows if, some day, in the not too far future, someone in a lab somewhere might "observe" a jittery proton, which is one of the biggest quanta.  In which case, both its location and momentum would be known deterministically.

Answer 2

to 'get a better grasp of it' is not adequate

people would need to discover something absolutely groundbreaking, and not yet predicted by models as far as i know

at that point it might be likely that QM will be made obsolete...

so probably not.

Answer 3

No.  Some things are truly random.  We can predict the probability of an event but cannot say exactly when an event will occur.

Information has an energy value.  If we pump enough energy into a system to know position and momentum, we have changed the system from its original state.  We cannot know the original state, that remains unknown.
