a, Geometry of the line array. b, Intensity landscape of traps for s = 3. c, Vibrational frequencies. The circles show the measured trap vibration frequencies of 19 kHz radial and 4 kHz axial. Plots used parameters d = 3 μm, s = 3, Ud = kB × 300 μK, Ta = 5 μK and λ = 825 nm. d, Plots of spatial localization. e, Map of measured variation in qubit frequency across the trap array, together with the measured shifts for the sites that were used relative to site q1. f, Ideal Gaussian beam intensity profile on a log scale.
