QubiC update 2025: expandability, versatility, modularity and usability
ORAL
Abstract
The QUantum BIt Control (QubiC) system is developed to control and readout superconducting qubits using FPGA technology from 2018. The latest version QubiC 2.0 is developed on Xilinx RFSoC evaluation board ZCU216 alongside a series of custom designed analog front end boards to meet the evolving requirement for different kinds of quantum processing units (QPUs). The hardware is packaged in standard 2U 19'' chassis and multiple chassis are synchronized to control larger QPUs. The FPGA gateware are refactored to streamline for a variety of configurations. The software APIs are updated together with more detailed documentation to improve the usability. Utilizing the QubiC system, research on the CPU-FPGA-QPU co-design has demonstrated significant reduced quantum circuits execution times.
