Can the surface properties of synthetic diamonds affect the quantum characteristics of (near-surface) NV centers? How should an experiment to measure this phenomenon look like? Finding answers to these intriguing questions is the focus of the QCI StarQ with Markus Mohr, Jakob Buchheim and their team from the Deutsches Zentrum für Luft-und Raumfahrt e.V.'s Institute for Quantum Technology. In the QCI StarQ project of the DLR Quantencomputing-Initiative (https://qci.dlr.de/starq), the influence of different surface modification and plasma treatments on (near-surface) NV center properties is investigated. Tailored modification of the chemical composition of the surface layer of diamond can lead to stabilization of NV centers which have great potential in combination with e.g. 13C nuclear spins to form quantum computing registers and qubits. The role of the team of quantum researchers within the Deutsches Zentrum für Luft-und Raumfahrt e.V. is the diamond surface modification, analysis of the chemical composition as well as the characterization of the NV center properties as part of the DLR Quantencomputing-Initiative. Diatope GmbH was commissioned to supply tailormade diamond material featuring NV centers in various depths from the surface. Novel fabrication techniques are developed to grow 12C enriched diamond material, free from spin noise and acting as a perfect host for carefully created NV centers in various depths ranging from a few to a few tens of nanometers. We are happy to share that we have successfully developed the first batch of NV diamonds, well designed to meet the project requirements and thoroughly characterized by our fabrication team including Yarden Hagian and Allegra de Gleria Clark.
