Emerging quantum technologies rely on the precise control of quantum systems, with diamond defects such as the negatively charged nitrogen-vacancy center showing promise for a range of applications. However, the unique properties of diamond present challenges, highlighting the need for advancements in materials science for characterization, growth, defect control, and fabrication in order to fully leverage diamond's potential for quantum technologies.
Emerging quantum technologies require precise control over quantum systems of increasing complexity. Defects in diamond, particularly the negatively charged nitrogen-vacancy center, are a promising platform with the potential to enable technologies ranging from ultra-sensitive nanoscale quantum sensors, to quantum repeaters for long distance quantum networks, to simulators of complex dynamical processes in many-body quantum systems, to scalable quantum computers. While these advances are due in large part to the distinct material properties of diamond, the uniqueness of this material also presents difficulties, and there is a growing need for novel materials science techniques for characterization, growth, defect control, and fabrication dedicated to realizing quantum applications with diamond. In this article we identify and discuss the major materials science challenges and opportunities associated with diamond quantum technologies.
