For the electrical characterization of superconducting quantum circuits there are two ³He/⁴He dilution inserts and one ³He system available at the WMI. The dilution inserts are installed in rf-shielded rooms and three-fold mumetal shields are used to reduce rf-noise and magnetic field noise. One of the inserts is used for spectroscopic measurements and is equipped with a semirigid coaxial line, which is thermally anchored at 4 K and still temperature. The other set up is used for time domain measurements of the coherent quantum dynamics of superconducting qubits and is equipped with several coaxial lines which allow to apply microwave pulses with frequencies up to 20 GHz. In both dilution inserts special care was taken to ensure optimal filtering of all biasing lines. Here, several filtering systems at different temperatures (room temperature, 4.2 K, still and base temperature) are used to reduce perturbing rf-noise. For the pre-characterization of Josephson junctions, qubits and other circuit elements we have set up a ³He insert allowing measurements down to 300 mK with fast cool down and warm up times.
