After three years of joint developments, the publicly BMBF-funded project MiLiQuant – Miniaturized Light Sources for Quantum Technology – expired. Led and coordinated by Q.ANT, the project aim of developing beam sources based on diode lasers to enable industrial use of quantum technologies was successfully achieved. The interdisciplinary consortium of science and industry with the project partners Bosch, Zeiss, Nanoscribe, Johannes Gutenberg University Mainz and the Paderborn University realized miniaturized, frequency- and power-stable beam sources. These lay the foundation for a multitude of applications in the fields of quantum sensing and novel imaging methods. With 10 Mio Euro, it in 2019 was one of the first high-volume projects in the German funding landscape, which were supported under the new German Quantum Initiative.
