Fast and Nanoscale Spin Control via Single Flux Quanta in Superconductors

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.
