  • Scalable characterisation of quantum states can be achieved by leveraging on simplifications valid for specific classes of states. Here, the authors show how to combine the strengths of shadows and many-body tomography for all states exhibiting exponential decay of correlations and the approximate Markov property.

  • Renormalisation group methods serve for finding analytic solutions, critical points and computing phase diagrams of many-body systems. Here the authors demonstrate that renormalisation group schemes can be constructed for undecidable many-body systems, giving rise to the types of renormalisation group flow which are strictly more unpredictable than chaotic flows.
