  Moving trapped-ion qubits in a microstructured array of radiofrequency traps
offers a route towards realizing scalable quantum processing nodes.
Establishing such nodes, providing sufficient functionality to represent a
building block for emerging quantum technologies, e.g. a quantum computer or
quantum repeater, remains a formidable technological challenge. In this review,
we present a holistic view on such an architecture, including the relevant
components, their characterization and their impact on the overall system
performance. We present a hardware architecture based on a uniform linear
segmented multilayer trap, controlled by a custom-made fast multi-channel
arbitrary waveform generator. The latter allows for conducting a set of
different ion shuttling operations at sufficient speed and quality. We describe
the relevant parameters and performance specifications for microstructured ion
traps, waveform generators and additional circuitry, along with suitable
measurement schemes to verify the system performance. Furthermore, a set of
different basic shuttling operations for dynamic qubit register reconfiguration
is described and characterized in detail.
