Electron-nuclear decoupling at a spin clock transition

Abstract The ability to design quantum systems that decouple from environmental noise sources is highly desirable for development of technologies with optimal coherence. chemical tunability electronic states in magnetic molecules combined advanced electron spin resonance techniques provides excellent opportunities address this problem. Indeed, so-called clock transitions have been shown protect molecular qubits noise, giving rise significantly enhanced Here we conduct a spectroscopic and computational investigation physics, focusing on the role nuclear bath. Away transition, linear coupling degrees freedom causes modulation decay coherence, as quantified via echo signals generated experimentally silico. Meanwhile, effective hyperfine interaction vanishes at resulting electron-nuclear decoupling an absence information leakage bath, providing characterize other decoherence sources.
