In our work, based on various arguments from complexity theory and physics, we demonstrate that a single Kerr mode can provide some \u2018quantum enhancements\u2019 when dealing with kernel-based methods. Using kernel properties, neural tangent kernel theory, first-order perturbation theory of the Kerr non-linearity, and non-perturbative numerical simulations, we show that quantum enhancements could happen in terms of convergence time and generalization error. Furthermore, we make explicit indications on how higher-dimensional input data could be considered. Finally, we propose an experimental protocol, that we call <jats:italic>quantum Kerr learning<\/jats:italic>, based on circuit QED.<\/jats:p>","DOI":"10.1088\/2632-2153\/acc726","type":"journal-article","created":{"date-parts":[[2023,3,23]],"date-time":"2023-03-23T22:45:24Z","timestamp":1679611524000},"page":"025003","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Quantum Kerr learning"],"prefix":"10.1088","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1669-8039","authenticated-orcid":true,"given":"Junyu","family":"Liu","sequence":"first","affiliation":[]},{"given":"Changchun","family":"Zhong","sequence":"additional","affiliation":[]},{"given":"Matthew","family":"Otten","sequence":"additional","affiliation":[]},{"given":"Anirban","family":"Chandra","sequence":"additional","affiliation":[]},{"given":"Cristian L","family":"Cortes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6590-9133","authenticated-orcid":true,"given":"Chaoyang","family":"Ti","sequence":"additional","affiliation":[]},{"given":"Stephen","family":"K Gray","sequence":"additional","affiliation":[]},{"given":"Xu","family":"Han","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2023,4,6]]},"reference":[{"year":"2020","author":"Huang","key":"mlstacc726bib1"},{"key":"mlstacc726bib2","doi-asserted-by":"publisher","first-page":"403","DOI":"10.1038\/s43588-021-00084-1","volume":"1","author":"Abbas","year":"2021","journal-title":"Nat.
