Coherence in a Hamiltonian eigenbasis yields asymmetry, the ability of a quantum system to break a dynamical symmetry generated by the Hamiltonian. We here propose an experimental strategy to witness multipartite entanglement in many-body systems by evaluating the asymmetry with respect to an additive Hamiltonian. We test our scheme by simulating asymmetry and entanglement detection in a three-qubit Greenberger\u2013Horne\u2013Zeilinger (GHZ) diagonal state.<\/jats:p>","DOI":"10.3390\/e19030124","type":"journal-article","created":{"date-parts":[[2017,3,16]],"date-time":"2017-03-16T11:24:28Z","timestamp":1489663468000},"page":"124","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Witnessing Multipartite Entanglement by Detecting Asymmetry"],"prefix":"10.3390","volume":"19","author":[{"given":"Davide","family":"Girolami","sequence":"first","affiliation":[{"name":"Department of Atomic and Laser Physics, University of Oxford, Parks Road, Oxford OX1 3PU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Yadin","sequence":"additional","affiliation":[{"name":"Department of Atomic and Laser Physics, University of Oxford, Parks Road, Oxford OX1 3PU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1345019","DOI":"10.1142\/S0217979213450197","article-title":"(Quantumness in the context of) resource theories","volume":"27","author":"Horodecki","year":"2013","journal-title":"Int.
