A Modular Multi-Card AWG Platform for High-Fidelity Control of Segmented Ion Traps — •Maximilian Orth1, 2, Björn Lekitsch1, 2, and Ferdinand Schmidt-Kaler1, 2 — 1QUANTUM, Institut für Physik, Johannes Gutenberg-Universität Mainz — 2neQxt GmbH
We present a new modular AWG platform for segmented ion traps, implemented as a multi-card system within a single chassis. DC-AWG, RF-AWG and main-controller cards are interconnected via a shared backplane, forming a freely scalable control architecture. The fully linear output behaviour allows for compensation and accurate modelling of the output distortion behind the trap*s filter network.
The DC-AWG cards provide 32 channels per module and a +-40V output. The main-controller card supplies deterministic digital I/O and system-wide timing with an update rate of 20ns, while the RF-AWG card generates the frequency-agile signals required for AOM/AOD-based laser-driven qubit gate operations. We also implement branching and looping, conditioned on counter input signals as required e.g. for quantum error correction. The DC AWG low noise floor enable accurate qubit register reconfiguration operations in complex shuttle-based trapped ion quantum processor architectures. This includes the transport, splitting/merging with multi-ion crystals.
