Quantum dots implemented in semiconducting nanowires offer control of their electronic configuration down to the single electron. This is possible thanks to their tightly confined electronic states that can be tuned by external gate voltages. We study the integration of nanowire quantum dots in superconducting planar resonators for their coupling and manipulation by microwave electromagnetic fields.
