The latter could be provided by superconducting circuits but existing solutions to interface the microwave and optical domains lack either scalability or efficiency, and in most cases the conversion noise is not known. In this work we utilize the unique opportunities of silicon photonics, cavity optomechanics and superconducting circuits to demonstrate a fully integrated, coherent transducer interfacing the microwave X and the telecom S bands with a total (internal) bidirectional transduction efficiency of 1.2% (135%) at millikelvin temperatures. The coupling relies solely on the radiation pressure interaction mediated by the femtometer-scale motion of two silicon nanobeams reaching a Vπ as low as 16 μV for sub-nanowatt pump powers. Without the associated optomechanical gain, we achieve a total (internal) pure conversion efficiency of up to 0.019% (1.6%), relevant for future noise-free operation on this qubit-compatible platform. https://research-explorer.ista.ac.at/download/8529/8530/2020_NatureComm_Arnold.pdf application/pdfno Springer Nature2020 eng General BiochemistryGenetics and Molecular BiologyGeneral Physics and AstronomyGeneral Chemistry Nature Communications 2041-1723 32901014 00057728020000110.1038/s41467-020-18269-z 11 https://research-explorer.ista.ac.at/record/13056 https://research-explorer.ista.ac.at/record/18871 https://doi.org/10.1038/s41467-020-18912-9 https://ist.ac.at/en/news/how-to-transport-microwave-quantum-information-via-optical-fiber/ Arnold, G.
