Rigid molecule of three cobalt ions aligned in a straight line and connected by metal–metal bonds serves as stable/ long-lived spin qubit

"spin state can change in response to external conditions such as temperature/ magnetic resonance control... Rabi oscillations demonstrated spin states coherently manipulated... molecule exhibits slow magnetic relaxation, with spin lifetimes long enough to meet key requirements for quantum information processing... electron spin not confined to single metal atom but delocalized across all 3 cobalt ions, helping stabilize quantum state... suppress unwanted vibrations, achieve longer spin lifetimes"
