This project is aimed at the development of the advanced technology and physics for the new generation of quantum devices based on few spin solid-state nano-systems. We will focus on few spin nano-systems in III-V semiconductors (quantum dots and nanowires) and carbon-based structures (carbon nanotubes, graphene and diamond), and also on development of new scientific equipment enabling advanced experiments.
The project has 4 major science and technology objectives, each embracing a number of III-V semiconductor and/or carbon-based structures: (1) Realization and optical control of coherent single spins in nanostructures; (2) Spin-orbit interaction and spin-orbit qubits in nanostructures; (3) Advanced techniques for manipulation of nuclear spins on the nanoscale; (4) Generation of long-distance entanglement between single spins.
The headline goals of this project include: electrically-driven single spin resonance, coherent population trapping in quantum dots, optically-addressable nano-magnetic systems, generation of long-distance entanglement between single spins, observation of magnetic order in spin nano-systems, self-polarization of nuclear spins, spin-orbit qubits in nano-structures, spin-echo measurements on a thousand nuclear spins, low-temperature lithography with sub-nanometer resolution, thermometry for micro-K regime. As this list shows, we intend to combine the fundamental studies of spin nano-systems with the development of new device concepts.The dedicated research programme will be carried out by 11 early stage researchers (396 person-months in total) and 5 experienced researchers (96 person-months), all gaining full access to the combined expertise of the 9 partner institutions, leading international players in the field of few spin solid-state nano-systems and advanced scientific instrumentation.
The extensive training programme will be based around many exchange visits between the partners and will benefit from 4 project meetings, 2 schools, and 2 conferences open for participation for the whole scientific community.
