ASTERIQS

Project Description

ASTERIQS is a collaborative research project awarded 9.75 Million Euro funding from the European Commission’s FET Flagship programme on Quantum Technology under the Horizon 2020 framework programme for Research and Innovation. The ASTERIQS project is developing precise sensors made from diamonds to measure quantities such as magnetic field, electric field, temperature or pressure.

Project objectives

Decade-long research activities in quantum sensing technologies have been bringing transformative advances to science, economy and society. In particular, quantum sensing exploits coherent superposition of quantum states to perform measurements with unprecedented sensitivity. Several platforms are being investigated, and among them, the negatively charged nitrogen-vacancy (NV-) colour centre in diamond allows for coherent manipulation of single spins in the solid-state at room temperature with simple optical read-out. Those characteristics are particularly attractive for applications outside of the laboratory.

The NV- centre in diamond is an excellent candidate to ultimately realise the ideal quantum sensor, namely a two-level system that coherently oscillates between two states and is affected only by a desired signal in the surrounding environment. Significant progress towards this goal has been achieved in the DIADEMS project, but ASTERIQS will provide new direction in terms of: deterministic implantation of nitrogen, atomically flat diamond surface and NV positioning less than 1 nm from the surface.
