Advanced Quantum Sensing with NanoDiamonds

钻石色心已经成为一个广泛使用的量子技术平台，包括信息处理，传感和计量，或光子学。这是由于它们独特的光学和自旋特性、长相干时间和对环境噪声的鲁棒性。纳米金刚石（NDs）是一种金刚石颗粒，其尺寸通常在几纳米到几百纳米之间，最近也引起了相当大的关注。NDs无毒，与各种环境兼容，表面易于修饰，易于集成到微系统中。这些特性使nd成为未来量子传感和生物医学成像应用的有希望的候选者。AQuSeND项目旨在开发适合NDs使用的新型量子传感协议。我们的目标是在这些纳米级材料中实现多模态传感能力，这些纳米级材料已经用于大块钻石，这将极大地扩展NDs的可能应用。为了实现这一目标，该项目将结合实验和理论方法来研究这种系统的特性，改进NDs材料的特性和所使用协议的性能，并开发其实际应用的新范围。该项目有望通过解锁NDs的多模态量子传感能力，为量子技术及其应用的进步做出重大贡献。这是一项雄心勃勃的跨学科努力，有可能取得令人兴奋的突破。预计最大的影响将在生物物理学和医学领域，纳米金刚石可以成为针对特定生物分子检测的传感器，并提供有关局部纳米级现象的详细信息，提供一种新的，无与伦比的诊断工具。

Diamond color centers have become a widely used platform for quantum technologies, including information processing, sensing and metrology, or photonics. It is due to their unique optical and spin properties, long coherence times, and robustness to the environmental noise. Nanodiamonds (NDs), which are diamond particles with sizes typically ranging from a few nanometers to a few hundred nanometers, have recently also gained considerable attention. NDs are non-toxic, compatible with various environments, their surface is easy to modify, and they can be integrated into microsystems easily. These properties make NDs a promising candidate for future applications in quantum sensing and biomedical imaging. AQuSeND project aims at the development of novel quantum sensing protocols tailored for use with NDs. Our goals is to enable multimodal sensing capabilities in these nanoscale materials that are already in use with bulk diamonds, and that will now vastly expand possible applications of NDs. To achieve this, the project will combine experimental and theoretical approaches to investigate the properties of such systems, improve NDs material properties and performance of the protocols used, and develop new range of their practical applications. This project is expected to significantly contribute to the advancement of quantum technologies and their applications by unlocking multimodal quantum sensing capabilities of NDs. It is an ambitious and interdisciplinary endeavor, with a potential for exciting breakthroughs. The greatest impact is expected in the fields of biophysics and medicine, where nanodiamonds can become sensors targeting the detection of specific biomolecules and giving detailed information about local nanoscale phenomena, offering a new, unparalleled diagnostic tool.
