This project aims to detect the tiny twisting forces imparted by a single quantum spin on a host diamond nanocrystal levitating in vacuum. Our team will build both a hypersensitive detector of quantum rotations and the complex theoretical models for quantum spin systems coupled to the mechanical motion of nanometre-sized diamonds. The expected experimental capabilities and knowledge generated by this project will enable world-first measurements of quantum effects with unparalleled sensitivity and powerful new quantum sensing paradigms. The project should enable significant benefits, such as incisive tests of the limits of quantum theory and new Australian technology operating at the interface of the quantum and classical worlds.

该项目旨在检测单个量子自旋对在真空中悬浮的宿主金刚石施加的微小扭曲力。我们的团队将建立一个超灵敏的量子旋转探测器和量子自旋系统的复杂理论模型，耦合到纳米尺寸钻石的机械运动。该项目产生的预期实验能力和知识将使世界上第一次测量量子效应具有无与伦比的灵敏度和强大的新量子传感范例。该项目将带来重大利益，例如对量子理论极限的深刻测试以及在量子和经典世界界面上运行的澳大利亚新技术。
