Our work in the divacancy defect in silicon carbide (SiC), another crystal defect-based electron spin qubit, has shown coherence times approaching 1.3 ms. This value is one of the longest T2 times of an electron spin in a naturally isotopic crystal, despite SiC having a higher nuclear spin density than naturally isotopic diamond.
