Nanowerk  October 8, 2024 Group-IV color centers in diamond are promising candidates for quantum networks. However, the magnetic dipole transitions required for microwave spin control are suppressed, and strain is necessary to enable these transitions. Researchers in Germany found substantial improvement when they utilized a superconducting coplanar waveguide to measure SnV centers subjected to strain. They demonstrated coherent spin manipulation and obtained a Hahn echo coherence time of up to 2=430  μ⁢s. With dynamical decoupling they could prolong coherence to about sixfold improvement compared to earlier works. They observed a nearby coupling spin, which might serve as a quantum memory, thus […]
