The scientists of RTG 3158 have formed an interdisciplinary network in the Laboratory of Nano and Quantum Engineering . The RTG 3158 builds a scientific bridge between the two clusters of excellence ‘Quantum Frontiers’ and ‘PhoenixD’, both led by LUH and significantly shaped by the physics research groups. All RTG project leaders are either members of QuantumFrontiers or PhoenixD and thus contribute the broad expertise and excellent infrastructure of both clusters of excellence to the RTG.
