Towards a large scale fully programmable trapped-ion quantum information processor

Long coherence times, high fidelity qubit state initialization and detection, and programmable long-range interactions make trapped ions a leading platform for quantum information processing (QIP). Here, we describe our recent development of a large-scale trapped-ion based quantum information processor. It is equipped with a multi-segmented blade electrode ion trap capable of trapping a large (>50) chain of Ytterbium ions in a near uniformly spaced configuration. Optimal vacuum system engineering has allowed us to design a vacuum vessel with simulated pressures of at least one order of magnitude lower than current room temperature trapped ion quantum information processor. A high numerical aperture (NA) holographic optical addressing system will be used for aberration-corrected addressing of the trapped ions with minimal 'crosstalk error' [1]. Such high-precision optical control will enable a wide range of QIP experiment from quantum simulations of reprogrammable, dynamical, and arbitrary lattice geometry of spins to researching problems in quantum error correction code.
