Therefore, if one chooses noncontextuality as one's notion of classicality, no-cloning cannot be regarded as a nonclassical phenomenon. In this work, however, we show that there are aspects of the phenomenology of quantum state cloning which are indeed nonclassical according to this principle. Specifically, we focus on the task of state-dependent cloning and prove that the optimal cloning fidelity predicted by quantum theory cannot be explained by any noncontextual model. We derive a noise-robust noncontextuality inequality whose violation by quantum theory not only implies a quantum advantage for the task of state-dependent cloning relative to noncontextual models, but also provides an experimental witness of noncontextuality.<\/jats:p>","DOI":"10.22331\/q-2020-04-27-258","type":"journal-article","created":{"date-parts":[[2020,4,27]],"date-time":"2020-04-27T16:34:19Z","timestamp":1588005259000},"page":"258","source":"Crossref","is-referenced-by-count":41,"title":["Contextual advantage for state-dependent cloning"],"prefix":"10.22331","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1942-2417","authenticated-orcid":false,"given":"Matteo","family":"Lostaglio","sequence":"first","affiliation":[{"name":"ICFO-Institut de Ciencies Fotoniques, The Barcelona Institute of Science and Technology, Castelldefels (Barcelona), 08860, Spain"},{"name":"QuTech, Delft University of Technology, P.O.
