Abstract: Atomic vapour cells are an indispensable tool for quantum technologies (QT), but potential improvements are limited by the capacities of conventional manufacturing methods. Using an additive manufacturing (AM) technique - vat polymerisation by digital light processing - we demonstrate, for the first time, a 3D-printed glass vapour cell. The exploitation of AM capacities allows intricate internal architectures, overprinting of 2D optoelectronical materials to create integrated sensors and surface functionalisation, while also showing the ability to tailor the optical properties of the AM glass by in-situ growth of gold nanoparticles. The produced cells achieve ultra-high vacuum of $2 \times 10^{-9}$ mbar and enable Doppler-free spectroscopy; we demonstrate laser frequency stabilisation as a QT application. These results highlight the transformative role that AM can play for QT in enabling compact, optimised and integrated multi-material components and devices.

Scalable construction of hybrid quantum photonic cavities [0.0]
We introduce a concept that generates a finely tunable PhC cavity at a select wavelength between two heterogeneous optical materials. The cavity is formed by stamping a hard-to-process material with simple waveguide geometries on top of an easy-to-process material. We simulate our concept for the particularly challenging design problem of multiplexed quantum repeaters based on arrays of cavity-coupled diamond color centers.

Machine-Learning-Assisted and Real-Time-Feedback-Controlled Growth of InAs/GaAs Quantum Dots [24.63252487293264]
Self-assembled InAs/GaAs quantum dots (QDs) have properties highly valuable for developing optoelectronic devices. The applications strongly rely on the density and quality of these dots, which has motivated studies of the growth process control to realize high-quality epi-wafers and devices. Here, we report a real-time feedback control method to realize the growth of QDs with arbitrary density, which is fully automated and intelligent.
