Quantum states of the light field are an indispensable building block of quantum technologies and at the same time of central importance for the investigation of fundamental aspects of physics. Entangled states of photons are used for applications in quantum communication, quantum cryptography, and quantum computing and allow both fundamental tests of quantum mechanics based on the violation of Bell's inequality and the investigation of fundamental aspects of quantum many-body physics. Tailor-made quantum states of the light field are also becoming increasingly important for high-precision measurements beyond the classical limit and promise integrated quantum photonics, whereby efficient generation, targeted guidance, tunable combination, and customized control of quantum states represent significant challenges that go far beyond the requirements of classical photonics. The Research Training Group (RTG) investigates the foundations for future hybrid, solid-state-based quantum photonics in an interdisciplinary collaboration of experimental and theoretical working groups, spanning the spectrum from the development of a fundamental understanding of individual quantum emitters to the generation of customized photon states and the research and implementation of novel photonic quantum systems based on integrated photonic circuits. In this way, the RTG not only offers doctoral researchers an extremely challenging, international research environment in basic research, but also provides doctoral researchers with interdisciplinary training in the fields of semiconductor physics, photonics, quantum information technology, and machine learning. Each of these future fields is already experiencing an enormous economic upswing, and their foreseeable merging will further increase the demand for the RTG's interdisciplinary doctoral researchers in science, industry, and society.The internationally orientated RTG will redesign a large number of courses for the specialist training of doctoral researchers, tailor them individually to the needs of doctoral researchers, and expand them with professional leadership development programs. The efficient structuring of the doctorate in conjunction with performance-related fast-track options and binding supervision agreements allow short doctoral periods. The already existing, diverse, international cooperations ensure access to excellent, international doctoral researchers and promote the independence of the doctoral researchers through networking and stays abroad. Intensive scientific exchange will be ensured by merging the doctoral researchers in the Laboratory of Nano and Quantum Engineering.
