Cole Comfort (May 14 2021 at 02:41):@Aleks Kissinger and I have put a paper on the arXiv which gives a universal set of generators for (affine) Lagrangian relations over a field. We show that affine Lagrangian relations over is Spekkens' toy model, and when is odd, this is p-dimensional qudit stabilizer circuits, up to scalars.
