Electrode configuration around the trap center. The ions are confined 70 μm above the surface using 10 DC control electrodes and one split RF electrode. The microwave conductor labeled MWM produces an oscillating magnetic near-field gradient in the \(\hat x\)\(\hat z\) plane in order to drive an entangling gate on two hyperfine qubits. The two microwave conductors labeled MWC can each generate an oscillating magnetic field for global manipulation of the spin state in the 2S1/2 manifold. Scale bar: 150 μm (bottom right)
