Programmable System for Laser Control of Trapped-Ion Experiments

Abstract

Modern quantum computing experiments demand exceptional precision, especially when controlling laser pulses for trapped-ion systems. Recent optical breakthroughs now pack dozens of channels onto a single chip, enabling efficient multichannel laser control. However, the supporting electronics often lack the necessary timing accuracy and flexibility. This shortfall can hinder progress and frustrate researchers. This thesis presents an FPGA-based laser control system on a Xilinx Zynq platform. A key module generates precise pulse waveforms and integrates into a system that delivers 32 pulsed and 32 static voltage signals. By leveraging dual-port block memories, state machines, and high-speed interfaces, the system achieves sub-microsecond timing with low resource usage. Simulation and board testing confirm accurate pulse generation while highlighting opportunities for enhanced precision and improved error handling. Overall, this work offers a reliable, scalable, and cost-effective solution for advanced FPGA applications in quantum control.
