Operation of a planar-electrode ion-trap array with adjustable RF electrodes

Abstract

One path to realizing systems of trapped atomic ions suitable for large-scale\nquantum computing and simulation is to create a two-dimensional array of ion\ntraps. Interactions between nearest-neighbouring ions could then be turned on\nand off by tuning the ions' relative positions and frequencies. We demonstrate\nand characterize the operation of a planar-electrode ion-trap array. Driving\nthe trap with a network of phase-locked radio-frequency (RF) resonators which\nprovide independently variable voltage amplitudes we vary the position and\nmotional frequency of a 40Ca+ ion in two dimensions within the trap array. With\nsuitable miniaturization of the trap structure, this provides a viable\narchitecture for large-scale quantum simulations.\n
