Electric field noise in surface ion traps

Trapped ions provide a suitable platform for quantum information applications due to their long coherence times and controllable quantum states. The planar Paul trap uses a flat surface with microfabricated electrodes to suspend ions in a harmonic potential. The benefit of this architecture is its scalability; it can be extended to create a fast, compact, multi-qubit system. However, an ion trapped close to a surface has increased sensitivity to electric field noise. This leads to so called ‘anomalous heating’ of the ions, thus limiting our ability to perform computations. We seek to characterize and remove the source of this noise. To this end, we are trapping ions with a diverse range of electrode materials and measuring the response of these materials to in-situ annealing and sputtering treatments.
