Given many identical copies of a quantum particle, what's the chance measuring their overall angular momentum yields zero? We show how to frame this problem as an optimization problem over a matrix group. We'll then discuss the relationship between this optimization problem and invariant theory, quantum tomography, and the Jacobian conjecture. This talk is based on the joint work https://arxiv.org/abs/2004.14872 with Michael Walter.
