Implementation of a Quantum Metamaterial

Understand

Manipulating the propagation of electromagnetic waves through sub-wavelength sized artificial structures is the core function of metamaterials.

• Resonant structures, such as split ring resonators, play the role of artificial "atoms" and shape the magnetic response.
• Superconducting metamaterials moved into the spotlight for their very low ohmic losses and the possibility to tune their resonance frequency by exploiting the Josephson inductance.
• Moreover, the nonlinear nature of the Josephson inductance enables the fabrication of truly artificial atoms.
