Interfaces based on cryogenic cavity electro-optic systems are particularly promising, due to the direct interaction between microwave and optical fields in the quantum regime. Quantum optical control of superconducting microwave circuits has been precluded so far due to the weak electro-optical coupling as well as quasi-particles induced by the pump laser. Here we report the coherent control of a superconducting microwave cavity using laser pulses in a multimode electro-optical device at millikelvin temperature with near-unity cooperativity. Both the stationary and instantaneous responses of the microwave and optical modes comply with the coherent electro-optical interaction, and reveal only minuscule amount of excess back-action with an unanticipated time delay. Our demonstration enables wide ranges of applications beyond quantum transductions, from squeezing and quantum non-demolition measurements of microwave fields, to entanglement generation and hybrid quantum networks.","lang":"eng"}],"file":[{"file_size":1349134,"date_created":"2023-07-10T10:10:54Z","success":1,"file_id":"13206","date_updated":"2023-07-10T10:10:54Z","creator":"alisjak","access_level":"open_access","file_name":"2023_NatureComms_Qiu.pdf","content_type":"application/pdf","checksum":"ec7ccd2c08f90d59cab302fd0d7776a4","relation":"main_file"}],"type":"journal_article","day":"24","article_processing_charge":"No","month":"06","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2024-08-07T07:11:55Z","pmid":1,"acknowledgement":"This work was supported by the European Research Council under grant agreement no. 758053 (ERC StG QUNNECT), the European Union’s Horizon 2020 research and innovation program under grant agreement no. 899354 (FETopen SuperQuLAN), and the Austrian Science Fund (FWF) through BeyondC (F7105).
