Abstract
We benchmark single-qubit gates in arrays of 87Rb atoms realized with radio-frequency (RF) and optical Raman exciation. We also show that thermal motion of an atom in tweezers leads to fast decay of Rabi oscillations for strongly focused Raman excitation and develop a simple numerical model describing the results. To perform a rigorous assessment of single-qubit gates quality we implemented a mirror randomized benchmarking protocol (RB) achieving fidelities over 0.99 for both RF and Raman excitation.
