  Two-dimensional arrays of optical micro-traps created by microoptical
elements present a versatile and scalable architecture for neutral atom quantum
information processing, quantum simulation, and the manipulation of ultra-cold
quantum gases. In this article, we demonstrate advanced capabilities of this
approach by introducing novel techniques and functionalities as well as the
combined operation of previously separately implemented functions. We introduce
piezo-actuator based transport of atom ensembles over distances of more than
one trap separation, examine the capabilities of rapid atom transport provided
by acousto-optical beam steering, and analyze the adiabaticity limit for atom
transport in these configurations. We implement a spatial light modulator with
8-bit transmission control for the per-site adjustment of the trap depth and
the number of atoms loaded. We combine single-site addressing, trap depth
control, and atom transport in one configuration for demonstrating the
splitting of atom ensembles with variable ratio at predefined register sites.
Finally, we use controlled sub-poissonian preparation of single trapped atoms
from such an ensemble to show that our approach allows for the implementation
of a continuous supply of single-atom qubits with high fidelity. These novel
implementations and their combined operation significantly extend available
techniques for the dynamical and reconfigurable manipulation of ultracold atoms
in dipole traps.
