A variety of quantum platforms have demonstrated a capacity for efficiently manipulating quantum states to simulate macroscopic properties or to implement quantum gates. High-fidelity quantum operations rely on the precise control over the quantum system in order to minimize possible error sources such as decoherence. Within the BMBF project FermiQP, we are working together with the group of Christian Groß in Tübingen, on optimizing protocols to transport via optical tweezers the neutral atoms trapped in a two-dimensional super lattice. Optimized protocols aim at maximizing the transport velocity while considering error sources coming from excitation of the motional ground state of the atom, the non-deterministic imperfections in the optical apparatus, coming from aberrations and diffraction in the tweezers, as well as the presence of further atomic wells in the lattice. We present first numerically optimized example trajectories for the atom transport and discuss potential improvements to the protocols.
