- Abstract summary: Trapped-ion quantum information processing may benefit from qubits encoded in isotopes that are practically available in only small quantities.
Laser ablation provides a method of controllably liberating neutral atoms or ions from low-volume targets.
Here we investigate ablation-based ion loading into surface-electrode traps of different sizes to test a model describing ion loading probability.

- Abstract: Trapped-ion quantum information processing may benefit from qubits encoded in
isotopes that are practically available in only small quantities, e.g. due to
low natural abundance or radioactivity. Laser ablation provides a method of
controllably liberating neutral atoms or ions from low-volume targets, but
energetic ablation products can be difficult to confine in the small
ion-electrode distance, micron-scale, microfabricated traps amenable to
high-speed, high-fidelity manipulation of ion arrays. Here we investigate
ablation-based ion loading into surface-electrode traps of different sizes to
test a model describing ion loading probability as a function of effective trap
volume and other trap parameters. We demonstrate loading of ablated and
photoionized barium in two cryogenic surface-electrode traps with 730 $\mu$m
and 50 $\mu$m ion-electrode distances. Our loading success probability agrees
with a predictive analytical model, providing insight for the confinement of
limited-quantity species of interest for quantum computing, simulation, and
sensing.

Most demanding application for a large-scale quantum computer will require ordered arrays.
By configuring an electronic-grade diamond substrate with a biased surface graphene electrode connected to charge-sensitive electronics, it is possible to demonstrate single ion implantation for ions stopping between 30 and 130nm deep from a typical ion source.
This allows the construction of ordered arrays of single atoms with associated colour centres that paves the way for the fabrication of deterministic colour center networks in a monolithic device.

We show how to implant low-energy ions into silicon devices featuring an enlarged 60x60 $mu$m sensitive area.
Despite the weak internal electric field, near-unity charge collection efficiency is obtained from the entire sensitive area.
This can be explained by the critical role that the high-quality thermal gate oxide plays in the ion detection response.
