In recent years superconducting qubits have opened up a new route to explore the physics of quantum metamaterials. Artificial materials, formed by many qubits, can potentially exhibit unusual and controllable refraction (transmission) coefficients in the microwave range. We have fabricated cavities and transmission lines containing 20 flux qubits and more. We experimentally investigate the transmission of electromagnetic waves through these new types of media. First experimental results will be presented and discussed.
