Integrated Photonics for Scalable Quantum Computers

Most quantum computing architectures in the future require highly integrated and precisely aligned photonic structures that are optimized for the operation of qubits . Entangled light can be generated in optical cavities, while interferometric coupling structures allow for manipulation of quantum states. The required wavelength range spans from UV to NIR, imposing significant technological demands on material selection, component design, manufacturing, and fabrication tolerances of integrated optical components. The goal of this project is to research the fabrication and characterization of scalable photonic components for signal generation, distribution, and manipulation on wafers and microchips.
