Heidelberg Quantum Architecture is a new experiment using ultracold Lithium-6 atoms aiming to achieve rapid cycle times of under one second. Among others, our approach is to speed up the MOT loading with more available laser power enabling the use of a high flux 2D MOT as well as a modular design with micrometer reproducibility.

In particular I will present setting up a laser lock to the Lithium-6 D2 transition using a modulation transfer scheme to ensure minimal drifts in frequency. An AOM Doublepass module enabling high stability and quick setup times is presented.

Physics in lower dimension often exhibits peculiar properties. Hence, we want to fine tune the dimentionality of the system using a miniaturized accordion lattice setup. It consists of two laser beams intersecting at a tunable angle. In this way controlling the spacing between the interference fringes, and therefore the strength of the confinement of our atoms.
