- Abstract
We present a design study into an ion trap electrode geometry for applying near-field microwave two-qubit gates. This design features an 'S'-shaped meander electrode to passively null the microwave field. It has ground planes separating the meander electrode from all of the DC and single-qubit microwave electrodes, which should reduce the sensitivity of the microwave field distribution to the boundary conditions of these electrodes. We show that it is possible to design a single-layer trap with this geometry such that the simulated microwave field null overlaps with the RF field null, and that the positions of these nulls can be simulated to a precision of 100 nm with moderate computing resources. We also show that such a trap can be designed such that ion chains can be trapped, transported and split with feasible DC and RF voltages. While this particular design is optimized for 43 Ca + ions, our approach could be applied to other ions by changing the microwave frequency to match the corresponding qubit transition frequency.
