Double resonance response of a superconducting quantum metamaterial: manifestation of non-classical states of photons

M. A. Iontsev, S. I. Mukhin, M. V. Fistul

We report a theoretical study of ac response of superconducting quantum metamaterials (SQMs), i.e. an array of qubits (two-levels system) embedded in the low-dissipative resonator.…
