I am sure I am misreading you again, but the equation is not
microscopic=quantum, macroscopic=classical. It can be very
well quantum=macroscopic. For instance, there is no classical
theory able to describe superfluidity, it must be quantum.
If I am misreading you again, let's say that I am doing this
remark for the other readers here ;)
