| 内容記述 | It is demonstrated that Silicon carbide (SiC) with a natural isotope abundance can preserve a coherent spin superposition in silicon vacancies over an unexpectedly long time exceeding 20 ms. The spin-locked subspace with a drastically reduced decoherence rate is attained through the suppression of heteronuclear spin crosstalking by applying a moderate magnetic field in combination with dynamic decoupling from the nuclear spin baths. Furthermore, Several phonon-assisted mechanisms of spin-lattice relaxation is identidied, and it is found that it can be extremely long at cryogenic temperatures, equal to or even longer than 10 s. | |||||
