Funding for Open Access provided by the UMD Libraries Open Access Publishing Fund.We have prepared meta-atoms based on radio-frequency superconducting quantum-interference devices (rf SQUIDs) and examined their tunability with dc magnetic field, rf current, and temperature. rf SQUIDs are superconducting split-ring resonators in which the usual capacitance is supplemented with a Josephson junction, which introduces strong nonlinearity in the rf properties. We find excellent agreement between the data and a model that regards the Josephson junction as the resistively and capacitively shunted junction. A magnetic field tunability of 80 THz=G at 12 GHz is observed, a total tunability of 56% is achieved, and a unique electromagnetically induced transparency feature at intermediate excitation powers is demonstrated for the first time. An rf SQUID metamaterial is shown to have qualitatively the same behavior as a single rf SQUID with regard to dc flux and temperature tuning.This work is supported by the NSF-GOALI Program through Grant No. ECCS-1158644 and the Center for Nanophysics and Advanced Materials (CNAM).

“…In addition, these waveguides and cavities may be combined with Josephson junctions and several of these compound elements may be arranged to form left-and right-handed transmission lines that exhibit tunable dispersion relations [21]. Moreover, suitably engineered Josephson junctions realize few-level * paolo.longo@kit.edu † peter.schmitteckert@kit.edu ‡ kurt.busch@kit.edu quantum systems for microwave photons whose coupling strength to the radiation field can be tuned to values that are simply not available in traditional quantum-optical systems at optical frequencies [22].…”

We analyze the role of quantum interference effects induced by an embedded two-level system on the photon transport properties in waveguiding structures that exhibit cutoffs (band edges) in their dispersion relation. In particular, we demonstrate that these systems invariably exhibit single-particle photon-atom bound states and strong effective nonlinear responses on the few-photon level. Based on this, we find that the properties of these photon-atom bound states may be tuned via the underlying dispersion relation and that their occupation can be controlled via multiparticle scattering processes. This opens an interesting route for controlling photon transport properties in a number of solid-state-based quantum optical systems and the realization of corresponding functional elements and devices.

“…1. A low loss left-handed transmission line (LHTL) can be realized with superconductors [19,20]. This is the dual (inductors and capacitors interchanged) of the usual [21] discrete representation of the right-handed transmission line (RHTL).…”

Quantum transmission lines are central to superconducting and hybrid quantum computing. In this work we show how coupling them to a left-handed transmission line allows circuit QED to reach a new regime: multimode ultrastrong coupling. Out of the many potential applications of this novel device, we discuss the preparation of multipartite entangled states and the simulation of the spin-boson model where a quantum phase transition is reached up to finite size effects.
