Long coherence time, programmable long-range interactions, and high fidelity state initialization and readout of trapped ions make them an excellent platform for quantum information processing (QIP).

Here, we show construction of a trapped-ion QIP device with multi-segmented blade-electrodes for anharmonic confining potentials of long chains of Yb ions (>50) with near-uniform inter-ion distance. 

Our design was optimized to reach pressure an order of magnitude below current room-temperature trapped-ion QIP devices, and for high-NA optical access.

We use holographic optical addressing with in situ aberration correction for coherent and incoherent operations on targeted ions with minimal crosstalk error [1].  

This device will allow us to perform a wide range of QIP experiments, from quantum simulations of dynamical spin-lattice systems to studies of quantum error correcting codes.
