BMBF Junior Research Group "QuSecure" Explores Quantum Communication


Dr. Tobias Heindel, physicist at the Institute of Solid State Physics, has succeeded in raising one of the coveted Junior Research Groups of the Federal Ministry of Education and Research (BMBF) as part of the "Quantum Futur" competition for young researchers. Equipped with an impressive budget of 2.2 million euros, he and his "QuSecure" Junior Research Group members will develop and research quantum communication systems over the next five years as part of the BMBF's "Photonics Research Germany" funding programme. In contrast to classical encryption technologies, quantum communication allows absolute security in data transmission. To this end, single-photon sources based on semiconductor quantum dots are first developed and optimized, which are then used to generate so-called "quantum keys". Besides the polarization of single light quanta, also their quantum-mechanical indistinguishability will be exploited in the laboratories, whereby novel and more powerful quantum cryptographic protocols can be implemented than previously possible. But the research will not (just) be limited to laboratory experiments. "As part of the "QuSecure" project, we are planning to set up a quantum communication network on the campus of the TU Berlin. Based on the developed quantum light sources and using different protocols for quantum key distribution, the aim is to test tap-proof communication in a realistic environment," explains Dr. Heindel.
