Toward a large-scale trapped ion quantum simulator with in-situ mid-circuit measurement

With long coherence times and relatively short gate times, the trapped ion platform has become a promising platform for quantum information processing (QIP). Here we show the progress of our segmented blade trapped-ion system with control of coherent and incoherent operations on individual Yb+ ions. We are developing a dual Acousto-Optic Deflector based Raman addressing system that is optimized for over thirty qubits, with low intensity crosstalk. We incorporate optical Fourier holography to create ~1E-4 intensity crosstalk of optical pumping and detection beams, and fast state detection for high-fidelity, in-situ mid-circuit measurement and resets. The vacuum chamber and its internals have been carefully prepared to achieve <1E-12 mbar pressure at room temperature, to maximize the lifetime of a long ion chain. This simulator will allow us to perform a wide range of QIP experiments, like measurement-based quantum simulations of spin Hamiltonian's and hybrid digital-analog quantum algorithms.
