In particular, high-dimensional spatial correlation has been used in several quantum information processing and sensing tasks, for instance, in ghost imaging experiments along with several quantum key distribution protocols. Here, we introduce a technique that exploits spatial correlations, whereby one can nonlocally access the result of an arbitrary unitary operator on an arbitrary input state without the need to perform any operation themselves. The method is experimentally validated on a set of spatially periodic unitary operations in one-dimensional and two-dimensional spaces. Our findings pave the way for efficiently distributing quantum simulations and computations in future instances of quantum networks where users with limited resources can nonlocally access the results of complex unitary transformations via a centrally located quantum processor.<\/jats:p>","DOI":"10.22331\/q-2025-09-11-1855","type":"journal-article","created":{"date-parts":[[2025,9,11]],"date-time":"2025-09-11T14:00:22Z","timestamp":1757599222000},"page":"1855","update-policy":"https:\/\/doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Nonlocal transfer of high-dimensional unitary operations"],"prefix":"10.22331","volume":"9","author":[{"given":"Dilip","family":"Paneru","sequence":"first","affiliation":[{"name":"Nexus for Quantum Technologies, University of Ottawa, K1N 5N6, Ottawa, ON, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Di Colandrea","sequence":"additional","affiliation":[{"name":"Nexus for Quantum Technologies, University of Ottawa, K1N 5N6, Ottawa, ON, Canada"},{"name":"Dipartimento di Fisica, Universit\u00e0 degli Studi di Napoli Federico II, Complesso Universitario di Monte Sant&apos;Angelo, Via Cintia, 80126 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessio","family":"D&apos;Errico","sequence":"additional","affiliation":[{"name":"Nexus for Quantum Technologies, University of Ottawa, K1N 5N6, Ottawa, ON, Canada"},{"name":"National Research Council of Canada, 100 Sussex Drive, Ottawa ON Canada, K1A 0R6"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ebrahim","family":"Karimi","sequence":"additional","affiliation":[{"name":"Nexus for Quantum Technologies, University of Ottawa, K1N 5N6, Ottawa, ON, Canada"},{"name":"National Research Council of Canada, 100 Sussex Drive, Ottawa ON Canada, K1A 0R6"},{"name":"Institute for Quantum Studies, Chapman University, Orange, California 92866, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"9598","published-online":{"date-parts":[[2025,9,11]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"R.
