I have been reading this explanation about(adsbygoogle = window.adsbygoogle || []).push({}); superpositions and mixtures. The author takes the example of two non-overlapping regions in space, each covered by a gaussian wavefunction. He goes on to compare the superposition and the mixture made up of those two gaussian functions, based on their different representations in terms of their density matrices.

My question is, how would one actually prepare a mixture exactly like the example discussed there?
