higher than I = 1/2. The ground states of these higher nuclear spin isotopes do not afford a simple
frequency selective preparation scheme on a strong transition, this limitation is circumvented by stroboscopicaly driving
strong and weak transitions. We demonstrate this method achieving a SPAM infidelity of < 1e-4,
allowing future systems to leverage naturally occurring isotopes with favorable wavelengths and
masses such as the 137Ba+ qubit used in this work. State preparation is performed by blending
standard, fast optical pumping using E1 transitions and narrow microwave or optical E2 transitions
addressing the extra states in the I=3/2 isotope of 137Ba+. Measurement is performed with repeated
coherent shelving to multiple metastable states.
