VTT Technical Research Centre of Finland Ltd coordinates Quantum e-leaps. VTT is a visionary research, development and innovation partner that helps the society and companies to grow through technological innovations. VTT has a strong commitment in quantum technology, and in Quantum e-leaps, VTT will focus on superconducting nanowire fabrication from disordered thin films, device integration, and metrology. Aalto University is a multidisciplinary research community, working in the fields of technology, business and art. At the Department of Applied Physics, the research focus is heavily on condensed matter and materials physics, and quantum physics. PICO group is specialized in mesoscopic physics and its sensor applications, in particular charge transport and thermal properties of metallic, superconducting and hybrid nanostructures. The group at ETH Zurich focuses on quantum devices realized in a solid-state environment. We explore the physics of correlated electron systems in confined geometries with the goal to find new routes for quantum information processing with solid-state qubits. Within the quantum e-leaps project we will develop twisted bilayer graphene systems displaying superconductivity which can be tuned by local gate arrangements. The Leibniz Institute of Photonic Technology (Leibniz IPHT) investigates biophotonic and quantum processes and systems with highest sensitivity and selectivity to address issues in the fields of medicine as well as life and environmental sciences. The Leibniz IPHT has a long-standing expertise in superconducting electronics technology and digital electronics and their application in high precision measurement systems, based on the institute’s well-equipped clean room facilities. These are playing a decisive role in the development of the new quantum phase slip junction and hybrid technologies within the Quantum e-leaps project. The National Physical Laboratory (NPL) is the UK’s national metrology institute. NPL’s mission is to provide the measurement capability that underpins the UK’s prosperity and quality of life. NPL provides confidence in measurement results and data traceable to SI units. Within the Quantum e-leaps project NPL will work on the implementation and validation of phase slip devices for metrology and disseminate the results to the international measurement community. Nanoscience is a research focus of the physics department at Regensburg university. About 20 workgroups target different aspects of nanostructures in solids along different directions such as topological insulators, 2d crystals, magnetism, light-matter interaction, quantum transport, superconductivity and other topics. Within Quantum e-leaps we contribute to 2d-superconducting technologies and device integration. Royal Holloway, University of London has a world class track record in superconducting quantum technologies. Nanophysics& Nanotechnology group established in 1996 has developed into a world leading research and technology laboratory in the field of superconducting quantum devices, a quantum limited sensors and microwave quantum photonics. The university has unique Nanofab facilities dedicated for fabrication of superconducting quantum devices.
