Fraunhofer Institute for Electronic Nano Systems
Single-photon sources are essential components for quantum communication, quantum cryptography, and quantum sensing.
The goal of the DeLiQuat project is the development of deterministic, i.e., specifically electrically excitable, single-photon sources based on quantum dots. Due to their electronic structure and the resulting photonic properties, inorganic quantum dots are excellent candidates for stable and innovative single-photon sources. Accordingly, in the DeLiQuat project, semiconductor quantum dots are integrated into a photonic chip to realize electronically controllable sources for a wide range of applications.
Key work packages include the assembly of individual quantum dots, the electrical and optical packaging of the sources, the design and setup of an optical system for coupling into optical waveguides, as well as the characterization of the respective sub-components. These tasks are being implemented in close cooperation with the project partners TU Chemnitz, TU Dresden, HTW Dresden, Fraunhofer IIS/EAS, and Fraunhofer ENAS.
