Les qubits au silicium dépassent 99.99% de fidélité avec trois unités actives

Les qubits de spin au silicium constituent une plateforme prometteuse pour la construction d'ordinateurs quantiques évolutifs, car ils sont compatibles avec les technologies de fabrication de semi-conducteurs utilisées pour produire les puces informatiques actuelles. Cependant, ils présentent une faiblesse importante : les qubits de spin au silicium perdent généralement en précision lorsque plusieurs qubits sont sous contrôle parallèle. Pour être utiles, les ordinateurs quantiques devront faire fonctionner de nombreux qubits simultanément sans compromettre la précision de leurs opérations.

Quantum calculations reveal how spin defects lose energySPIN DEFECT DRAIN

Quantum calculations reveal how spin defects lose energy

When light hits a tiny defect embedded in a solid material like diamond or silicon carbide, it can kick the defect's electrons into an excited state. These spin defects have the potential to be used as stable, readable qubits for quantum technologies, for example, quantum sensing. But modeling the full physics of their energetics over time—a key step in developing spin defects into new technologies—is a challenging task.
