In contrast to nonlinear optics, electro-optic devices so far require classical modulation fields whose variance is dominated by electronic or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional single-sideband conversion of X band microwave to C band telecom light with a microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of less than or equal to 0.074 photons. This is facilitated by radiative cooling and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures. The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output noise photons per second for the highest available pump power of 1.48 mW puts near-unity efficiency pulsed quantum transduction within reach. Together with the non-Gaussian resources of superconducting qubits this might provide the practical foundation to extend the range and scope of current quantum networks in analogy to electrical repeaters in classical fiber optic communication."}],"oa":1,"oa_version":"Published Version","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2021-02-12T10:41:28Z","publisher":"American Physical Society","title":"Bidirectional electro-optic wavelength conversion in the quantum ground state","quality_controlled":"1","related_material":{"link":[{"url":"https://ist.ac.at/en/news/how-to-transport-microwave-quantum-information-via-optical-fiber/","relation":"press_release","description":"News on IST Homepage"}],"record":[{"id":"13071","relation":"research_data","status":"public"},{"id":"12900","relation":"dissertation_contains","status":"public"},{"status":"public","id":"13175","relation":"dissertation_contains"}]},"status":"public","doi":"10.1103/prxquantum.1.020315","author":[{"first_name":"William J","last_name":"Hease","full_name":"Hease, William J","id":"29705398-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9868-2166"},{"id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87","full_name":"Rueda Sanchez, Alfredo R","first_name":"Alfredo R","last_name":"Rueda Sanchez","orcid":"0000-0001-6249-5860"},{"orcid":"0000-0001-6264-2162","full_name":"Sahu, Rishabh","id":"47D26E34-F248-11E8-B48F-1D18A9856A87","last_name":"Sahu","first_name":"Rishabh"},{"orcid":"0000-0001-6613-1378","id":"45598606-F248-11E8-B48F-1D18A9856A87","full_name":"Wulf, Matthias","last_name":"Wulf","first_name":"Matthias"},{"orcid":"0000-0003-1397-7876","full_name":"Arnold, Georg M","id":"3770C838-F248-11E8-B48F-1D18A9856A87","first_name":"Georg M","last_name":"Arnold"},{"full_name":"Schwefel, Harald G.L.","first_name":"Harald G.L.","last_name":"Schwefel"},{"first_name":"Johannes M","last_name":"Fink","full_name":"Fink, Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8112-028X"}],"publication":"PRX Quantum","has_accepted_license":"1","external_id":{"isi":["000674680100001"]},"publication_identifier":{"issn":["2691-3399"]},"ec_funded":1,"article_type":"original","citation":{"mla":"Hease, William J., et al. “Bidirectional Electro-Optic Wavelength Conversion in the Quantum Ground State.” <i>PRX Quantum</i>, vol. 1, no. 2, 020315, American Physical Society, 2020, doi:<a href=\"https://doi.org/10.1103/prxquantum.1.020315\">10.1103/prxquantum.1.020315</a>.","ieee":"W.
