"large quantum system's information spreads/ becomes chaotic/ inaccessible causing high error rates, overcome using Krylov winding enabling quantum systems to retain memory of their initial states even under intense scrambling conditions... error correction, more reliable complex problem solving,  exponentially faster... new framework for applied mathematics and computational science, potentially leading to more robust quantum architectures in the near future"
