DESCRIPTION:Building blocks for photonic quantum technologies\nKai Müller\, Technical University of Munich\n\nAbstract: \nPhotonic quantum technologies rely on the ability to generate\, process\, and detect quantum states of light with high efficiency and fidelity. Therefore\, realizing building blocks for these tasks does not only require highly pure materials and state of the art nanofabrication but moreover to develop a deep understanding of the underlying physical processes. This talk will present insights into the dynamics of generating quantum states of light from optically active few-level quantum systems\, represented by semiconductor quantum dots [1-3]. Moreover\, progress in pushing the limits of superconducting nanowire single photon detectors via local He-ion irradiation will be discussed [4-5] as well as the potential of atomically thin materials for the detection of single photons in the far infrared regime [6]. Finally\, an integrated photonics platform for quantum memories based on Er:CaWO4 will be presented [7]. \n[1] L. Hanschke et al.\, npj Quantum Information 4\, 43 (2018) \n[2] F.
