Abstract:
Here, we propose a modular framework for representing and generating voltage solutions for near-term ion trap devices. Voltage graphs are separated into individual segments interconnected by shuttling paths through junctions managed by a Finite State Machine (FSM). This representation then maps onto a modular hardware architecture capable of driving up to 24 96-channel segments at 10MSPS with 10,000 voltage lines per channel. Multi-channel synchronous DACs denoted as 'Arbitrary Path Generators' (APG) store the electrode voltages corresponding to each voltage line in a lookup table and execute path traversal sequences. A segment controller then directs the APG to execute a specific shuttling sequence as defined by the graph. Lastly, a trap controller is used to coordinate actions among multiple segments. We also explore the efficient generation and simulation of trap solutions for long-chain systems.
