Quantum technology
The worldwide progress in quantum technology makes the first broader applications seem realistic in the very near future. The IIM is engaged in materials research on platforms for qubits. In particular, qubits based on defects in semiconductors (e.g. Si, SiC etc.) or 2D materials (e.g. hBN) can be generated in a controlled and targeted manner by ion implantation. This will be used to investigate spin-based qubits as well as systems for emission of single or entangled photons, primarily integrated on silicon substrates (CMOS compatible) and at telecom wavelengths. The coupling of electronic, optical, magnetic, as well as nanomechanical elements into hybrid quantum systems becomes a central key to addressing and controlling qubits in more complex systems and coupling them to existing core electronic and photonic technologies.
In the field of quantum sensing, we are concerned with high-sensitivity imaging of magnetic structures in solids (e.g., domain walls, skyrmions), as well as detection of magnetic fields in biological systems. Furthermore, these quantum sensors can be integrated into opto-electronic circuits or nanostructures, enabling fast magnetic field, current and temperature measurements with high sensitivity under extreme operating conditions with potential applications in industry.
