One Hundred Years Later: Stern-Gerlach Experiment and Dimension Witnesses

Inspired by the one-hundredth anniversary of seminal works Stern and Gerlach, our contribution is a proposal how to use their famous experiment in more contemporary perspective. Our main idea re-cast modern language prepare-and-measure scenarios. By doing so, it possible connect geometric algebraic aspects space states with physical space. We also discuss simulations SG as well some experimental properties revealed at statistical level. Merging perspective paradigmatic experiment, we hope this paper can serve an entry door for quantum information theory the.
