The whole problem with quantum mechanics these days is that it’s gotten so you can’t find the line separating quantum physics from classical physics. It’s not really correct to say that quantum mechanics is relegated to the very small or minuscule. It’s a dichotomy that Schrodinger’s Cat presents: Can quantum mechanics affect things in the macro world? And does observing collapse the waveform? We have recently seen how the same *quantum superposition* that’s found in the Schrodinger’s Cat experiment was employed by the Chinese scientists in achieving the new world record for quantum teleportation. So, obviously great distances can be involved, although the particles involved were very small, in that case. Unlike old school quantum mechanics view that relegated phenomena to very small distances, e.g., quantum confinement in nanoscale dimensions, I.e., deBroglie wavelength. Is it classical physics? Or is it quantum mechanics? You decide.
