The newly approved GRK 3158 project aims to develop the foundations for novel photonic quantum chips.

On May 1, 2026, a new Research Training Group will launch at LUH, building a scientific bridge between the two Clusters of Excellence QuantumFrontiers and PhoenixD. Colleagues from the Institutes of Solid-State Physics, Photonics, Gravitational Physics, and Theoretical Physics will collaborate on research into the fundamentals of quantum states of the light field for photonic applications in quantum communication, quantum cryptography, and quantum computing. The Research Training Group aims to develop solid-state-based, hybrid quantum photonics with tailored control of complex quantum states. The first funding period runs until April 30, 2031, with two cohorts of ten doctoral students each receiving funding from the DFG. The spokesperson for the Research Training Group is Michael Oestreich from the Institute of Solid State Physics.

The German Research Foundation (DFG) has approved the Research Training Group (RTG) 3158 ‘Quantum Photonics: Quantum Emitters, Tailor-Made Photon States and Quantum Processors’. With the Research Training Groups the DFG contributes to the funding of researchers in the early stages of their careers for a maximum period of nine years.

Quantum states of light are the driving force behind future quantum technologies. Entangled photons enable tap-proof communication, novel computers and ultra-precise measurements – and provide tests of fundamental physics beyond classical limits. The new GRK 3158, spokesperson Prof. Dr. Michael Oestreich, Institute of Solid State Physics at LUH, combines experimental and theoretical expertise for this purpose. The goal is hybrid, solid-state-based quantum photonics: from a deep understanding of individual quantum emitters to the generation of tailor-made photon states to novel quantum systems on integrated photonic circuits.

The participating PhD students work in a cutting-edge international environment and receive interdisciplinary training in semiconductor physics, photonics, quantum information technology and machine learning. This combination provides them with optimal preparation for careers in science, business and society. Individually tailored courses, leadership development programmes, clear supervision agreements and fast-track options ensure efficient doctoral programmes. Existing global collaborations open up access to excellent applicants, promote stays abroad and encourage networking. Close scientific exchange is ensured by bringing researchers together in the Laboratory for Nano- and Quantum Engineering. The initial funding period will last for five years.
