A Clock Transition in the Cr7Mn Molecular Nanomagnet
A Clock Transition in the Cr7Mn Molecular Nanomagnet
A viable qubit must have a long coherence time $T_2$. In molecular nanomagnets $T_2$ is often limited at low temperatures by the presence of dipole and hyperfine interactions, which are often mitigated through sample dilution, chemical engineering and isotope substitution in synthesis. Atomic-clock transitions offer another route to reducing decoherence …
