The past decade has witnessed remarkable progress in quantum information sciences, made possible in part by advances in materials science, and ultra-sensitive measurement techniques that enable exquisite control of individual quantum entities, e.g., photons, atoms, and spins. As these technologies continue to mature, they are expected to revolutionize computation, metrology, communication, photonics and electronics. In the proposed work, we will apply ultra-sensitive nanowire-based magnetic resonance force microscopy—a technique pioneered in my group—for high-resolution imaging and spectroscopy of electron and nuclear spins. ***We are proposing to build the first nanometer scale magnetic resonance imaging (nano-MRI) platform capable of imaging and controlling individual spins in solids. This capability, unique in the world, will allow us to address fundamental problems previously inaccessible using other techniques. In the coming years, nano-MRI will revolutionize structural biology by allowing us to image protein molecules and virus particles with atomic resolution and chemical specificity—a capability that will play a crucial role in the development of new drugs and treatments for diseases. Nano-MRI will enable new materials discovery by revealing the organization of spins in nanoscale devices and material interfaces, and help address fundamental questions in quantum information sciences by allowing us to unravel the complex quantum interactions of single spins with their environment. ***The proposed projects require the development of a suite of cutting edge techniques in ultra-sensitive force-detected magnetic resonance spin detection, unique to Canada and the world. The HQP trained on these projects will possess the diverse technical background necessary to secure highly sought after positions in industry and academia. The support provided by NSERC, along side our expertise in nano-MRI, and the extensive capabilities at the Institute for Quantum Computing will ensure Canada's competitive edge in the rapidly developing field of quantum technologies.
