Quantum modification: Utilizing accelerators to implant single atoms for biosensing (French Edition)

In the field of quantum technology, accelerators have been intensively applied within the last decade to modify and characterize materials. Accelerator-based techniques use high-energy ions to alter atomic structures in materials, which allows scientists to control the behaviour of single atoms. The main use of accelerators has been in ion implantation, which is a widely used technique in the semiconductor industry and has been around for decades. "For semiconductors, a high number of ions are implanted to change the electrical properties of, for example, silicon," explained Andrew Bettiol, Associate Professor at the National University of Singapore. "For quantum technologies, we have a very different aim. We want to control the ions at the single ion level. We are not implanting millions or billions of ions; we are implanting exactly one ion."
