“…Figure 4 a) shows heating rate measurements as a function of position for a trap containing waveguides and gratings that supported 435 nm light delivery. 9 All positions of the ion, from the loading location, to the region where waveguide light was incident upon the ion at a ∼ 45 degree angle, to directly above the grating showed similar heating rates. Notably, the layer of oxide which covers the output gratings and was exposed to the ion through an aperture cut into the top metal of the trap, did not cause significant heating.…”

“…Continued scaling of surface ion traps to larger numbers of trapped ions will require new solutions to the delivery and collection of light. [7][8][9] This becomes even more critical as traps move to two-dimensional arrays of ions, limiting optical access from the side. We're addressing this challenge through the integration of optical waveguides into the dielectric below the electrodes of the ion trap.…”

As trapped ion systems add more ions to allow for increasingly sophisticated quantum processing and sensing capabilities, the traditional optical-mechanical laboratory infrastructure that make such systems possible are in some cases the limiting factor in further growth of the systems. One promising solution is to integrate as many, if not all, optical components such as waveguides and gratings, single-photon detectors, and high extinction ratio optical switches/modulators either into ion traps themselves or into auxiliary devices that can be easily integrated with ion traps. Here we report on recent efforts at Sandia National Laboratories to include integrated photonics in our surface ion trap platforms.

We describe the design of a surface-electrode ion trap junction, which is a key element for large-scale ion trap arrays. A bi-objective optimization method is used for designing the electrodes, which maintains the total pseudo-potential curvature while minimizing the axial pseudo-potential gradient along the ion transport path. To facilitate the laser beam delivery for parallel operations in multiple trap zones, we implemented integrated optics on each arm of this X-junction trap. The layout of the trap chip for commercial foundry fabrication is presented. This work suggests routes to improving ion trap junction performance in scalable implementations. Together with integrated optical addressing, this contributes to modular trapped-ion quantum computing in interconnected 2-dimensional arrays.

“…One of the most common trapping geometries for ions, the linear Paul trap, confines ions to motion in a 1D harmonic potential [26]. Another geometry using surface electrodes is emerging as a platform for quantum computing, and can be engineered to generate tunable potentials [27] or to couple to light [28]. In both trap geometries, it is possible to load a small number of ions, or even a single ion, into the trap.…”

Using a non-perturbative classical model, we numerically investigate the dynamics of mobile particles interacting with an infinite chain of harmonic oscillators, an abstraction of ionic conduction through solid-state materials. We show that coupling between the mobile particles and a single mass of the chain is sufficient to induce dissipation of the mobile particles' energy over a wide range of system parameters. When we introduce thermal fluctuations in the position of the chain mass, the mobile particles exhibit thermalization, eventually reaching the same temperature scale as the chain. This model demonstrates how a minimal set of ingredients can exhibit a link between microscopic motion and macroscopic observables, with computationally efficient simulations. Finally, we suggest some experimental platforms that could realize such a model.
