Virtual photons lead to a transverse interaction between qubits when they are nonresonant with the cavity but resonant with each other. We experimentally investigate the inverse scaling of the interqubit coupling with the detuning from a cavity mode and its proportionality to the qubit-cavity interaction strength. We demonstrate that the enhanced coupling at higher frequencies is mediated by multiple higher-harmonic cavity modes. Moreover, we observe dark states of the coupled qubit-qubit system and analyze their relation to the symmetry of the applied driving field at different frequencies.","lang":"eng"}],"issue":"6","acknowledgement":"This work was supported by the Swiss National Science Foundation (SNF), the Austrian Science Foundation (FWF), and ETH Zurich","quality_controlled":0,"day":"22","publisher":"American Physical Society","_id":"1781","publication_status":"published","volume":83}
