Visualizing large quantum states

As quantum simulations are able to prepare increasingly more complex many-body states, it remains a challenge to visualize and analyze such states. The cases of large single-qudit states and permutationally symmetric multi-qubit states have been addressed in a recent study published in Physical Review A which has been caried out by Bálint Koczor (University of Oxford), Robert Zeier (Forschungszentrum Jülich), and Steffen J. Glaser (Technical University of Munich). Highly-optimized approches to compute spherical phase-space functions are provided which are at least an order of magnitude faster than traditional methods. These advances make it feasible to effectively illustrate large quantum states occuring in theoretical explorations and experimental quantum simulators. This will foster future experimental progress in generating complex many-body states.
