The paragraph immediately following the one you quote still does make claims of quantum advantage: &quot;Our second order OTOC circuits introduce a minimal structure while remaining sufficiently generic that circumvents this challenge by exploiting the exponential advantage provided by including time inversion in the measurement protocol, see arXiv:2407.07754.&quot; The advantage claimed by the paper isn&#x27;t about Hamiltonian learning (i.e extracting model parameters from observational data), but instead about computing the expectation value of a…</p><p><a href="https://hackerpaper.kaipfister.de/p/2407.07754/">Paper and discussion history</a>.
