Interacting Rydberg Ions

Trapped Rydberg ions are a novel approach for quantum information processing [1]. This idea merges two highly developed quantum technologies, trapped ions and Rydberg atoms, with advantages from both sides. In particular, it combines the precise quantum control of trapped ions and the strong dipolar interactions of Rydberg atoms [1-3]. For trapped ions, this technology promises to speed up entanglement operations and make them available in larger ion crystals.
