Rabi spectroscopy in a qubit-oscillator system — •Julian Hauss, Alexander Shnirman, and Carsten Hutter — Institut für Theoretische Festkörperphysik, Universität Karlsruhe, D-76128 Karlsruhe, Germany

In recent years coherent control of JJ-qubits was demonstrated in many experiments. A promising approach towards efficient non-demolition measurement of a JJ-qubit is the readout via a harmonic oscillator coupled to the qubit. In particular, Rabi spectroscopy experiments in such systems were carried out in Jena.

We analyzed theoretically the Rabi spectroscopy in a qubit-oscillator system. We studied the contributions of one- and two-photon processes to the spectroscopic signal and made a comparison with the experimental results.
