Its advantage is particularly evident at low signal powers, a promising feature for applications such as noninvasive biomedical scanning or low-power short-range radar. Here, we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path. Starting from experimental data, we also simulate the case of perfect idler photon number detection, which results in a quantum advantage compared with the relative classical benchmark. Our results highlight the opportunities and challenges in the way toward a first room-temperature application of microwave quantum circuits."}],"publication_identifier":{"eissn":["23752548"]},"doi":"10.1126/sciadv.abb0451","author":[{"first_name":"Shabir","full_name":"Barzanjeh, Shabir","last_name":"Barzanjeh","orcid":"0000-0003-0415-1423","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Pirandola","full_name":"Pirandola, S.","first_name":"S."},{"last_name":"Vitali","full_name":"Vitali, D","first_name":"D"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","last_name":"Fink","first_name":"Johannes M"}],"volume":6,"_id":"7910","external_id":{"isi":["000531171100045"],"arxiv":["1908.03058"]},"project":[{"_id":"26336814-B435-11E9-9278-68D0E5697425","name":"A Fiber Optic Transceiver for Superconducting Qubits","grant_number":"758053","call_identifier":"H2020"},{"call_identifier":"H2020","grant_number":"862644","name":"Quantum readout techniques and technologies","_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E"},{"_id":"258047B6-B435-11E9-9278-68D0E5697425","name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics SUPEREOM","grant_number":"707438","call_identifier":"H2020"},{"call_identifier":"H2020","grant_number":"732894","name":"Hybrid Optomechanical Technologies","_id":"257EB838-B435-11E9-9278-68D0E5697425"},{"name":"Integrating superconducting quantum circuits","_id":"26927A52-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"F07105"}],"date_published":"2020-05-06T00:00:00Z","publication":"Science Advances","publication_status":"published","day":"06","file_date_updated":"2020-07-14T12:48:05Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file":[{"relation":"main_file","access_level":"open_access","file_name":"2020_ScienceAdvances_Barzanjeh.pdf","date_created":"2020-06-02T09:18:36Z","checksum":"16fa61cc1951b444ee74c07188cda9da","file_id":"7913","creator":"dernst","content_type":"application/pdf","date_updated":"2020-07-14T12:48:05Z","file_size":795822}],"related_material":{"record":[{"id":"9001","relation":"later_version","status":"public"}],"link":[{"url":"https://ist.ac.at/en/news/scientists-demonstrate-quantum-radar-prototype/","description":"News on IST Homepage","relation":"press_release"}]},"license":"https://creativecommons.org/licenses/by/4.0/","intvolume":"         6","quality_controlled":"1","language":[{"iso":"eng"}],"oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"}}
