Two superconducting qubits collectively emit their radiation to a fast on chip microwave transmission line resonator. The quantum state of the field can be fully characterized by a matrix representation in the photon number basis. (Image: Jonas Mlynek, Quantum Device Lab, ETH Zurich)

The image shows microchips fabricated in the FIRST clean-room facilities at ETH Zurich. The background photograph depicts a set of microwave resonators that are used to store and manipulate single or multiple microwave photons. In the foreground a false-color microscope image of a superconducting artificial atom (zick-zack structure) which is integrated into such a resonator is shown together with an artist's impression of two photons traveling along the resonator and approaching the artificial atom.
