I read often that the transition from quantum to classical, the fact that there normally no macroscopic quantum objects are observed, has only become clear with the proper understanding of the decoherence mechanism.
But what about Broglie wavelength!? Physicists knew before, that macroscopic objects do not show ( or are very very unlikely to show) quantum behavior such as interference or tunneling due to Broglie wavelength, since momentum of big object make Broglie wavelength negligibly small.
So am I right to assume that the problem of quantum-to-classical transition before decoherence explanations was not about position and momentum, but strictly about finite dimensional superposition, like a|alive> + b|dead>?
thank you
