Such device-independent techniques have been proposed to certify the quality of entangled states, unitary operations, projective measurements following von Neumann's model and rank-one positive-operator-valued measures (POVM). Here, we show that they can be extended to the characterization of quantum instruments with post-measurement states that are not fully determined by the Kraus operators but also depend on input states. We provide concrete certification recipes that are robust to noise.<\/jats:p>","DOI":"10.22331\/q-2020-03-19-243","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T13:31:53Z","timestamp":1584624713000},"page":"243","source":"Crossref","is-referenced-by-count":33,"title":["Device-independent characterization of quantum instruments"],"prefix":"10.22331","volume":"4","author":[{"given":"Sebastian","family":"Wagner","sequence":"first","affiliation":[{"name":"Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland"}]},{"given":"Jean-Daniel","family":"Bancal","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland"}]},{"given":"Nicolas","family":"Sangouard","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland"}]},{"given":"Pavel","family":"Sekatski","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Basel, Klingelbergstrasse 82, CH-4056 Basel, Switzerland"}]}],"member":"9598","published-online":{"date-parts":[[2020,3,19]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"B.
