Paving the way to a scalable device for quantum information processing

Paving the way to a scalable device for quantum information processing: Researchers have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits. The research shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine individual ions at the nanoscale.
