Ytterbium-171 has isolated nuclear spin-½–a native qubit with second-scale coherence times; while its narrow-line electronic transitions open a playground for MHz-scale manipulations on the single qubits, low-entropy state-preparation and fast readout. Employing microsecond-scale control of the clock transition and site-selectivity enabled by tweezer light shifts, we can shelve a subset of qubits to the clock state and measure the reminder; we will report our progress using this technique to realize mid-circuit measurements along with lossless state-sensitive detection.
