Cold-atom physics has reached unprecedented control over atomic degrees of freedom. Atoms can be slowed down and trapped by electromagnetic fields. Electronic and spin states of atoms as well as collective quantum states of ultra-cold gases can be manipulated with high fidelity. Complex quantum simulations, atomic clocks and interferometers hallmark the developments of the field. Interfacing ultra-cold atoms and solids promises novel quantum interfaces where electronic, magnetic or mechanical degrees of freedoms may be transferred from one system to the other while preserving the quantum nature. Atoms may probe quantum properties of electric currents or sense mechanical vibrations of nano-objects, and may serve as functional units of quantum electronic circuits or as transducer between quantum electronics and optics. Along these lines I present experimental results on interfacing ultra-cold atoms with superconducting circuits and on spectroscopy of electromagnetic noise with an atom laser.
