OutlineWhat do you do when your qubit
frequency is too close to your cavity? “Quantum art”
• Response of a coupled qubit-cavity system to a strong drive at finite temperature– Singly dressed - qubit + cavity– Doubly dressed system –
• qubit+cavity+ drive• two photon processes
– Triply dressed• three photon processes
“2½D” - Transmon coupled to microstrip cavity• Standard large-pad transmon,
GHz• Measured with microstrip cavity
– Measured at 20 mK– Radiation decay suppressed due to
