Abstract
We perform coherent population trapping (CPT) experiments to measure the hyperfine coupling of a single 73GeV to be A∼37 MHz. Furthermore, we identify a rapid nuclear spin diffusion process that occurs when performing CPT and leverage it to realise all-optical, arbitrary nuclear state preparation at timescales approaching ∼1 μs. This is a fundamental step in gaining access to the otherwise difficult to address nuclear spin qudit and paves the way for future research regarding the 73GeV.
