The fabrication of scalable quantum devices in diamond relies on the ability to produce optical centres with a high spatial resolution. Ion implantation is the most powerful technique for placing impurity atoms in a diamond matrix. Pezzagna et al. ( pp. 2017–2022 ) present a novel approach by implanting ions through a mask with high‐aspect‐ratio nano‐channels and improve the collimation to below 50 nm. The mask contains parallel oriented channels of a few tens of nm in diameter. They are produced by exposing mica sheets to GeV heavy ion projectiles and subsequent track etching. The high‐resolution creation of deep nitrogenvacancy centres in diamond by implanting nitrogen ions through the nano‐channels is demonstrated.
