The collapse of the quantum wave function – in which quantum objects go from existing within many possible states at once to settling into a concrete one understood by classical physics – does ...

As Schrödinger himself pointed out, it's unclear how the wave function goes from a cloud of probabilities before measurement to simply not existing the moment we make an observation.

Knowing the wave function of such a quantum system is a challenging task—this is also known as quantum state tomography or quantum tomography in short.

Although long-term wave observation data is required to analyze waves, only shortterm observation data is available in Korea because observation systems have been established in Korea since 2001.
