In this work, we demonstrate a solution to this problem by using a frequency multiplier to drive the qubit with room-temperature control pulses at half or one third of the qubit frequency fQB. The control pulses are up-converted inside the cryogenic environment using a frequency multiplier based on a high-kinetic inductance nonlinear transmission line. We evaluated the success of the up-conversion technique by comparing the randomized benchmarking error-per-gate metrics to that of a standard direct qubit driving technique. The fQB/2 drive technique achieved error rates consistent with the direct drive, with a minimum error-per-gate of 3.5x10\u22123\u00b10.4x10\u22123. The fQB/3 drive technique resulted in a minimum error per gate of 7.6x10\u22123\u00b10.81x10\u22123. While this demonstration is based around a fQB = 4.836 GHz qubit so that a direct drive comparison is possible, this technique will allow higher-frequency qubits to be tested using existing radio-frequency (RF) infrastructure.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/4118_README.txt", "mediaType": "text/plain", "title": "4118_README"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig2.json", "mediaType": "application/json", "title": "fig2"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig3.json", "mediaType": "application/json", "title": "fig3"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig5_left.txt", "mediaType": "text/plain", "title": "fig5_left"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig5_right.txt", "mediaType": "text/plain", "title": "fig5_right"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig6_direct_drive.txt", "mediaType": "text/plain", "title": "fig6_direct_drive"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig6_doubler.txt", "mediaType": "text/plain", "title": "fig6_doubler"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig6_tripler.txt", "mediaType": "text/plain", "title": "fig6_tripler"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig7.json", "mediaType": "application/json", "title": "fig7"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-4118/fig8.json", "mediaType": "application/json", "title": "fig8"}], "identifier": "ark:/88434/mds2-4118", "issued": "2026-05-05", "keyword": ["Frequency conversion.", "Superconductors", "kinetic inductance"], "landingPage": "https://data.nist.gov/od/id/mds2-4118", "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2026-02-26 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "theme": ["Electronics:Superconducting electronics"], "title": "Superconducting Qubit Control Using Cryogenic Frequency Conversion"}
