In parallel, quantum error correction codes that can protect quantum information encoded in rotational states of a single molecule have been developed. These codes are currently an abstract concept, as no implementation strategy is yet known. Here, we present a step towards experimental implementation of one family of such codes, namely absorption-emission codes. We first construct architecture-agnostic check and correction operators. These operators are then decomposed into elements of the quantum logic spectroscopy toolbox that is available for molecular ions. We then describe and analyze a measurement-based sequential as well as an autonomous implementation strategy in the presence of thermal background radiation, a major noise source for rotation in polar molecules. The presented strategies and methods might enable robust sensing or even fault-tolerant quantum computing using the rotation of individual molecules.<\/jats:p>","DOI":"10.22331\/q-2024-12-27-1578","type":"journal-article","created":{"date-parts":[[2024,12,27]],"date-time":"2024-12-27T17:03:22Z","timestamp":1735319002000},"page":"1578","update-policy":"https:\/\/doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Strategies for implementing quantum error correction in molecular rotation"],"prefix":"10.22331","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7535-1874","authenticated-orcid":false,"given":"Brandon J.","family":"Furey","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8188-7701","authenticated-orcid":false,"given":"Zhenlin","family":"Wu","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6996-7916","authenticated-orcid":false,"given":"Mariano","family":"Isaza-Monsalve","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-0217-5117","authenticated-orcid":false,"given":"Stefan","family":"Walser","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9681-6667","authenticated-orcid":false,"given":"Elyas","family":"Mattivi","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7533-6126","authenticated-orcid":false,"given":"Ren\u00e9","family":"Nardi","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9461-9650","authenticated-orcid":false,"given":"Philipp","family":"Schindler","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Experimentalphysik, Universit\u00e4t Innsbruck, Technikerstra\u00dfe 25\/4, 6020 Innsbruck, Austria"}]}],"member":"9598","published-online":{"date-parts":[[2024,12,27]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"J.
