Coupling a Superconducting Qubit to a Left-Handed Metamaterial Resonator
Coupling a Superconducting Qubit to a Left-Handed Metamaterial Resonator
Metamaterial resonant structures made from arrays of superconducting lumped-circuit elements can exhibit microwave-mode spectra with left-handed dispersion for the standing-wave resonances, resulting in a high density of modes in the same frequency range where superconducting qubits are typically operated, as well as a bandgap at lower frequencies that extends down …
