Researchers at the National University of Singapore have developed hourglass-shaped nanographene molecules that can store and process information using multiple interacting spins. By using carbon-based frameworks instead of metal atoms, these molecules offer longer spin coherence times and better chemical versatility. This design strategy allows for precise control over magnetic properties, making these carbon structures promising candidates for molecular qubits and quantum simulators. The study highlights a specific molecular structure that is highly resilient to magnetic perturbations, a key requirement for stable quantum information technology.
