Many-Body Quantum Scar (IMAGE) Institute of Science and Technology Austria Caption At the bottom one can see 10 atoms oscillating between ground state (black) and excited state (white). Since this is a quantum system, atoms can be simultaneously in the superposition of all possible 47 configurations. Top plot shows the different probabilities of these individual configurations over time.
