advanced_notions:quantum_mechanics:decoherence

Macroscopic systems are part of warm and wiggly environments, and the constant interactions scramble up quantum links between parts of the system. This scrambling—called decoherence—quickly converts quantum states to normal probability distributions, even in the absence of a measurement apparatus. Decoherence thus explains why we don’t observe superpositions of large things. The cat isn’t both dead and alive; there’s just a 50 percent probability that it’s dead. Lost in Math by Sabine Hossenfelder

In this section things should be explained by analogy and with pictures and, if necessary, some formulas.

The motto in this section is: *the higher the level of abstraction, the better*.
