Gold nanoclusters could offer tunable qubits

QuantumDaily says atomically precise gold nanoclusters can act as “super atoms,” with spin and optical properties set by their structures. It says changing the surrounding ligand molecules took spin polarisation from 7% to nearly 40%, and that a team aims to stiffen that shell to extend coherence time. The post presents this tunability as a possible route to more stable, scalable qubits.
