It's or at least fundamentally it's like the phase-based point rather than the distribution.
It represents physical features of the system being studied, different quantum states um
represent different physical features the system might have.
Um
But I'm reluctant to go from that and say the phase space point the the quantum state is itself physically real.
For the same reason I'm reluctant to say that the phase space point is physically real.
I mean the phase space point is a convenient mathematical representation.
Um what's it's a you know it's it's a mathematical entity.
What's physically real are the various physical systems
That the phase space is.
is representing
and the particular properties that the physical systems have.
that the particular phase space point is representing.
So if I'm doing quantum field theory, for instance, what's real are the points of space time and the quantum fields on that space time, which have lots of very complicated nonclassical properties.
Which properties do they have at any given moment in time?
Well
The quantum state tells you.
But I think it's an error to think, to to say that the quantum state itself
Exists or is real.
Or is physical in that story.
