text: The strong atomistic spin–orbit coupling of holes makes single-shot spin readout
measurements difficult because it reduces the spin lifetimes. By integrating the
charge sensor into a high bandwidth radio frequency reflectometry setup, we were
able to demonstrate single-shot readout of a germanium quantum dot hole spin and
measure the spin lifetime. Hole spin relaxation times of about 90 μs at 500 mT
are reported, with a total readout visibility of about 70%. By analyzing separately
the spin-to-charge conversion and charge readout fidelities, we have obtained
insight into the processes limiting the visibilities of hole spins. The analyses
suggest that high hole visibilities are feasible at realistic experimental conditions,
underlying the potential of hole spins for the realization of viable qubit devices.
