For the latter, we utilize a persistent current flux qubit. We characterize the tunable and switchable coupling in the frequency and time domains and find that the coupling between the relevant modes can be varied in a controlled way. Specifically, the coupling can be tuned by adjusting the flux through the qubit loop or by controlling the qubit population via a microwave drive. Our measurements allow us to find parameter regimes for optimal coupler performance and quantify the tunability range.2015http://zaguan.unizar.es/record/4181310.1103/PhysRevB.91.014515http://zaguan.unizar.es/record/41813oai:zaguan.unizar.es:41813info:eu-repo/grantAgreement/ES/MINECO/FIS2012-36673-C03-02PHYSICAL REVIEW B 91, 1 (2015), 014515 [6 pp]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
