However, artificial giant atoms interact with that field at multiple points, which opens up new, interesting quantum abilities.
A new study explores the applications of giant superatoms (GSAs) and shows how they can provide a compelling platform for quantum information processing.
This is true of natural atoms, but also some artificial ones like Rydberg atoms, quantum dots, and superconducting qubits.
When you put multiple giant atoms together, you get a decoherence-free transfer of quantum states (decoherence being when a quantum system loses its quantum qualities through things like thermal noise).
In the braided configuration, the GSAs displayed improved efficiency at swapping quantum information while (crucially) maintaining coherence.
