Abstract: Despite tremendous progress in quantum information processing towards prototypical devices and early attempts at showing quantum utility, there remain a number of outstanding technical challenges. State of the art quantum computers based on neutral atoms take up substantial space, harkening back to the vacuum tube era of classical computing. Reducing the spatial requirements of these machines by transitioning to more integrated architectures is an important goal as these technologies mature. Here we demonstrate two key steps in this direction. First, a quantum register of Cs single atom qubits is prepared using a 1225-site optical trap array formed with only passive optics, removing the need to use active electro-optic devices for trap pattern formation. The trap pattern is formed using an amplitude mask combined with a Fourier filtering setup, and can be adapted to create dark traps, bright traps, or both interleaved, using only a single trapping wavelength. Secondly, we show progress towards a rudimentary two-node quantum network of Rb atoms, which is a stepping stone towards the modularization of quantum processors. The network employs nodes with a novel fiber-coupled design and integrated optics, reducing the experimental footprint and leading to superior mechanical stability. We present design and construction techniques used for building the nodes as well as initial results with trapped single atoms.
