Light-matter interaction in acoustic systems with giant atoms

Researchers at Chalmers University of Technology in Sweden and the Max Planck Institute for the Science of Light explored the interaction between a large artificial atom and acoustic fields with wavelengths several orders of magnitude below the atomic dimensions.

The approach adopted by the scientists could be compared to controlling an atom’s radiation by attaching it to an antenna. The researchers were able to demonstrate the non-exponential decay and the novel scattering properties of giant atoms.

By coupling with superconducting circuits, they hope to create complex quantum states which could be used for simulating solid-state quantum systems or certain schemes to realize quantum computing. (
