- KIT researchers optically initialized, controlled, and read out nuclear spin states in a molecular material for the first time, leveraging europium ions' narrow optical transitions.
- Nuclear spins are highlighted as particularly stable quantum information carriers due to their weak interaction with the environment, achieving quantum coherence with a lifetime of up to two milliseconds.
- Professor David Hunger emphasizes that molecular materials offer a promising platform for future quantum components, enabling stable and dense qubit registers by addressing nuclear spins without electron spin interference.
- Professor Mario Ruben's group at KIT synthesized the molecular crystals, tailoring them for atomically precise qubit registers and investigating their suitability for quantum platforms.
Why it matters: This research is a crucial step towards optically networked quantum processing systems and scalable quantum computers.
