Projekt

The project aims at the fabrication and testing of devices from diamond, targeting two main applications: The development of a dedicated quantum memory for the implementation of quantum coins and quantum sensing of magnetic fields. With the deterministic nano implantation system nuclear spins will be integrated next to nitrogen vacancy and silicon vacancy colour centres in diamond such that long lived quantum states can be stored and entangled for increased security. The theoretical part will enhance the protection of the quantum coin by identifying decoherence-free subspaces (DFS). This improves the quality of the quantum coin but also allows for the realization of sensors that are protected against environmental noise with increased sensitivity to signals outside of the DFS, providing the design principle for sensitive and selective nano gradient sensors.
