We show analytically that in the quasiclassical regime the entanglement growth rate can be simply computed by means of the underlying classical dynamics. Furthermore, this rate is given by the Kolmogorov\u2013Sinai entropy, which characterizes the dynamical complexity of classical motion. Our results, illustrated by numerical simulations on a model of coupled rotators, establish in the quasiclassical regime a link between the generation of entanglement, a purely quantum phenomenon, and classical complexity.<\/jats:p>","DOI":"10.3390\/e25010097","type":"journal-article","created":{"date-parts":[[2023,1,4]],"date-time":"2023-01-04T05:02:30Z","timestamp":1672808550000},"page":"97","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Entanglement Dynamics and Classical Complexity"],"prefix":"10.3390","volume":"25","author":[{"given":"Jiaozi","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Physics, University of Osnabr\u00fcck, D-49069 Osnabr\u00fcck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8251-6531","authenticated-orcid":false,"given":"Barbara","family":"Dietz","sequence":"additional","affiliation":[{"name":"Center for Theoretical Physics of Complex Systems, Institute for Basic Science (IBS), Daejeon 34126, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9747-1033","authenticated-orcid":false,"given":"Dario","family":"Rosa","sequence":"additional","affiliation":[{"name":"Center for Theoretical Physics of Complex Systems, Institute for Basic Science (IBS), Daejeon 34126, Republic of Korea"},{"name":"Basic Science Program, Korea University of Science and Technology (UST), Daejeon 34113, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0510-0524","authenticated-orcid":false,"given":"Giuliano","family":"Benenti","sequence":"additional","affiliation":[{"name":"Center for Nonlinear and Complex Systems, Dipartimento di Scienza e Alta Tecnologia, Universit\u00e0 degli Studi dell\u2019Insubria, Via Valleggio 11, 22100 Como, Italy"},{"name":"Istituto Nazionale di Fisica Nucleare, Sezione di Milano, Via Celoria 16, 20133 Milano, Italy"},{"name":"NEST, Istituto Nanoscienze-CNR, 56126 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1655","DOI":"10.1098\/rsta.2003.1227","article-title":"Quantum technology: The second quantum revolution","volume":"361","author":"Dowling","year":"2003","journal-title":"Phil.
