  text: One of the most promising approaches towards large-scale quantum computation
    uses devices based on many Josephson junctions. Yet, even today, open questions
    regarding the single junction remain unsolved, such as the detailed understanding
    of the quantum phase transitions, the coupling of the Josephson junction to the
    environment or how to improve the coherence of a superconducting qubit. Here we
    design and build an engineered on-chip reservoir connected to a Josephson junction
    that acts as an efficient bolometer for detecting the Josephson radiation under
    non-equilibrium, that is, biased conditions. The bolometer converts the a.c. Josephson
    current at microwave frequencies up to about 100 GHz into a temperature rise measured
    by d.c. thermometry. A circuit model based on realistic parameter values captures
    both the current–voltage characteristics and the measured power quantitatively.
    The present experiment demonstrates an efficient, wide-band, thermal detection
    scheme of microwave photons and provides a sensitive detector of Josephson dynamics
    beyond the standard conductance measurements.
