The shape of higher-dimensional state space: Bloch-ball analog for a qutrit
Geometric intuition is a crucial tool to obtain deeper insight into many concepts of physics.A paradigmatic example of its power is the Bloch ball, the geometrical representation for the state space of the simplest possible quantum system, a two-level system (or qubit).However, already for a three-level system (qutrit) the state space has eight dim
