Infinite number of quantum particles gives clues to big-picture behavior at large scale

In quantum mechanics, measuring both the position and speed of a particle at the same time is not possible. To identify a particle's characteristics, physicists introduced the notion of quasi-distribution of position and momentum. In a new study scientists have reversed this approach; starting with quantum mechanical rules, they explore how to derive an infinite number of quasi-distributions, to emulate the classical mechanics approach.
