information science; the I = 1/2 nuclear spin in 171Yb is emerging as a promising system in
which to implement a qubit. With an array of atoms in tweezers at the magic trapping wavelength for the optical clock transition, we demonstrate repeated, nondestructive readout of the nuclear spin states, and present Rabi oscillations generated by a rotating magnetic field with second-scale decay rates. We combine these capabilities to realize several textbook paradigms, such as the non-commutativity of repeated measurements in different bases, and to demonstrate the quantum Zeno effect by alternating qubit rotations and measurements. Finally, we present work on excitation to the metastable “clock” state and coherently convertible, dual-type nuclear spin qubits, as well as efforts toward remote entanglement generation. These results constitute an important step towards resource- and time-efficient measurement-based quantum computation and, with the metastable nuclear spin qubit, telecom-band quantum networking.
