Quantum mecahnics: Nature's trick to avoid having to be Newtonian-precise

This sounds like a "null experiment": Testing that things we suspect are true are actually true.

After all, the whole attempt at building quantum computers is based on the idea that the complex-valued probability density function is an element of a (non-classical) reality, which we are going to damn well exploit the fuck out of.

The system's absence of a classical state before measurement (i.e. before extraction of a few classical bits) clearly follows in the footsteps of Anton Zeilinger's GHZ states, which I frankly can't remember the details of.

“we can't easily simulate quantum systems on a classical computer.”

Indeed so. You can do it, but with exponential slowdown. And not for continuous systems. The question of whether a continuous wave function even exists in nature is open and will probably remain so forever, after all you cannot measure it.
