Yet, even today, open questions regarding the single junction remain unsolved, such as the detailed understanding of the quantum phase transitions, the coupling of the Josephson junction to the environment or how to improve the coherence of a superconducting qubit. Here we design and build an engineered on-chip reservoir connected to a Josephson junction that acts as an efficient bolometer for detecting the Josephson radiation under non-equilibrium, that is, biased conditions. The bolometer converts the a.c. Josephson current at microwave frequencies up to about 100 GHz into a temperature rise measured by d.c. thermometry. A circuit model based on realistic parameter values captures both the current–voltage characteristics and the measured power quantitatively. The present experiment demonstrates an efficient, wide-band, thermal detection scheme of microwave photons and provides a sensitive detector of Josephson dynamics beyond the standard conductance measurements.","lang":"eng"}],"type":"journal_article","scopus_import":"1","article_type":"original","project":[{"_id":"eb9b30ac-77a9-11ec-83b8-871f581d53d2","name":"Protected states of quantum matter"}],"_id":"17480","publication_status":"epub_ahead","author":[{"full_name":"Karimi, Bayan","last_name":"Karimi","first_name":"Bayan"},{"last_name":"Steffensen","full_name":"Steffensen, Gorm Ole","first_name":"Gorm Ole"},{"full_name":"Higginbotham, Andrew P","last_name":"Higginbotham","orcid":"0000-0003-2607-2363","first_name":"Andrew P","id":"4AD6785A-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Marcus, Charles M.","last_name":"Marcus","first_name":"Charles M."},{"first_name":"Alfredo","full_name":"Levy Yeyati, Alfredo","last_name":"Levy Yeyati"},{"full_name":"Pekola, Jukka P.","last_name":"Pekola","first_name":"Jukka P."}],"publication_identifier":{"eissn":["1748-3395"],"issn":["1748-3387"]},"day":"22","publication":"Nature Nanotechnology","date_updated":"2024-09-06T09:14:52Z","ddc":["530"],"title":"Bolometric detection of Josephson radiation","doi":"10.1038/s41565-024-01770-7","quality_controlled":"1","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","main_file_link":[{"url":"https://doi.org/10.1038/s41565-024-01770-7","open_access":"1"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"}}
