Contents and goals

Quantum physical phenomena enable novel applications in science and technology that lead to significant improvements in information processing. In particular, quantum communication is already technologically mature for real application scenarios. Using Quantum Key Distribution (QKD), it is possible to dramatically increase data security in new digital business areas such as smart grids, personalized medicine or micro-transaction banking. Thus, quantum-based secure communications can become the locational advantage of a data-driven economy. However, many quantum communication scenarios so far only achieve low electro-optical integration density and key rates in the low kbit range. The overall goal of our FastPhoton research group is to advance quantum communications by focusing on high-frequency control of photon sources in high-performance opto-electronic components and assemblies. We target applications of optical quantum-based data communication in fiber optic and satellite networks.
