In a recent article in Science, we have proposed a new concept in the theory of many-body entanglement: entanglement polytopes. They are built from single-particle information; yet, surprisingly, they lead to powerful predictions about the entanglement present in a quantum states. Here we would like to invite you to explore the entanglement polytopes of small quantum systems. For more details, please consult our article or the preprint.
