Group-IV color centers in diamond are promising candidates for quantum networks due to their dominant zero-phonon line and symmetry-protected optical transitions that connect coherent spin levels. The negatively charged tin-vacancy (SnV) center possesses long electron lifetimes its large spin-orbit splitting. However, the magnetic dipole required microwave control suppressed, strain is necessary enable these transitions. Recent work has shown of strained emitters using lines suffer from...
Quantennetzwerke zur Verteilung verschränkter Zustände könnten künftig sichere Kommunikation, vernetzte Quantensensoren und die Verknüpfung von Quantencomputern ermöglichen. Dafür werden langlebige Quantenspeicher benötigt, effizient mit Licht adressiert können. Unser Team konnte nun erstmals einem supraleitenden Mikrowellenleiter volle Quantenkontrolle lange Quantenspeicherzeiten für ein einzelnes Zinn‐Fehlstellenzentrum in Diamant demonstrieren.
