We study a generic cavity-QED system where a set of (artificial) two-level dipoles is coupled
to the electric field of a single-mode LC resonator. This setup is used to derive a minimal …

Demonstrating a device that efficiently connects light, motion, and microwaves is an
outstanding challenge in classical and quantum photonics. We make significant progress in …

Quantum battery (QB) is the miniature energy storage and release device and plays a
crucial role in future quantum technology. Here an implementation scheme of a QB is …

Superinductors have a characteristic impedance exceeding the resistance quantum RQ≈
6.45 k Ω, which leads to a suppression of ground-state charge fluctuations. Applications …

With the introduction of superconducting circuits into the field of quantum optics, many
experimental demonstrations of the quantum physics of an artificial atom coupled to a single …
