Project description
Controlling electron spin through a magnetic vortex
Electron spin control is key to unleashing the potential of spintronics, quantum sensing and quantum information processing. Control of the rate of spin transitions determines the fidelity of quantum states and the accuracy in quantum sensing applications. Addressing individual spins with high spatial resolution is essential for scaling quantum computers. The EU-funded FastoSpintrolux project plans to optically manipulate single vortices (optical tweezers) to address individual spins. By rapidly passing a vortex and its strong field through the spin target, researchers will swiftly tune the spin resonance and coherently drive spin transitions at gigahertz rate. The project will enhance our understanding of the coupling between mesoscopic flux quanta and single qubits and provide efficient methods of entangling multiple spins via optically driven vortices.
Objective
Quantum control of spin qubit plays a key role in spintronics, quantum sensing and quantum information processing. The spin control rate determines the quantum state fidelity and the accuracy in quantum sensing, and thus needs to be enhanced for many applications. Meanwhile, building scalable quantum technology often involves densely distributed qubits, which requires the feasibility of addressing individual spins with high spatial resolution. In order to cope with the growing demand for the operational rate and spatial precision, the experienced researcher proposes to use single flux quanta (Abrikosov vortices) in superconductors to individually address the electronic spin of nitrogen-vacancy (NV) centers with far-field optics. Optical manipulation of single vortices like optical tweezers enable the nanoscale addressability of individual spins. By rapidly passing a vortex and its strong field through the spin target, he aims at swiftly tuning the spin resonance and coherently driving spin transitions with gigahertz rate. This proposal opens new possibilities of exploring the coupling between mesoscopic flux quanta and single qubits, and provides a promising method for efficiently entangling multiple spins via optically driven Abrikosov vortices.
