Is it Gaussian? Testing bosonic quantum states
Filippo Girardi, Freek Witteveen, Francesco Anna Mele +4
Gaussian states are widely regarded as one of the most relevant classes of continuous-variable (CV) quantum states, as they naturally arise in physical systems and play a key role…

Thirty-six officers, artisanally entangled
David Gross, Paulina Goedicke
A perfect tensor of order is a state of four -level systems that is maximally entangled under any bipartition. These objects have attracted considerable attention in quantum…

Wigner's Theorem for stabilizer states and quantum designs
Valentin Obst, Arne Heimendahl, Tanmay Singal +1
We describe the symmetry group of the stabilizer polytope for any number of systems and any prime local dimension . In the qubit case, the symmetry group coincides with the…
