SEM image of the T-type superconducting quantum network with 10 flux qubits.
CNR-SPIN (M. Lisitskiy) and CNR-ISASI (B. Ruggiero), have carried out a study of collective quantum dynamics of a superconducting quantum network (SQN) embedded in resonators in the regime of substantial disorder.

A collective quantum state takes place when the interaction between qubits overcomes the disorder in the qubit frequencies which gives rise to a drastic increase of the amplitude of the dominant resonance. The complete article, in collaboration with LNF INFN Frascati (C. Gatti), is available here.
