SPINUS Initial communication kit
Quantum advancement: SPINUS aims to demonstrate a quantum simulator with 50+ quantum units and a quantum computer with 10+ qubits. Also, SPINUS seeks scale them up to more than 1000 quantum units and 100 qubits, respectively, within two years post-project.
SiC investigation: SPINUS will investigate SiC as a platform for spin-based quantum simulation and computing. This could allow for qubit/unit counts to exceed 100 and 1000, respectively, opening up the possibility to compete or even surpass existing technologies.
Strategic advantage: SPINUS will strengthen this position and foster collaboration between European institutions, building a common pan-European knowledge base on spin-based quantum simulation and computing.
Theoretical support for fundamental quantum operations.
Developing large coupled spin networks in 2D and 3D for prototype quantum simulators.
Creating a quantum computation platform using materials from WP1 and WP2.
Raising awareness of the potential of quantum technologies, contributing to business development, and standardization.
Ensuring qualitative, timely, and cost-efficient administration of the entire project.
