This paper presents RISC-Q, an open-source generator for quantum control system-on-chips built with SpinalHDL and a RISC-V-compatible programming interface. Its claim is that the generator can reproduce the performance of existing custom controllers with less development effort, which matters for groups that need to iterate on control hardware for different qubit platforms. The evidence so far is a demonstration of replication, so the practical value will depend on how well the design performs on real quantum hardware and how widely the toolchain is adopted.
RISC-Q: A Generator for Real-Time Quantum Control System-on-Chips Compatible with RISC-V
arXiv:2505.14902v2 Announce Type: replace-cross Abstract: Quantum computing imposes stringent requirements for the precise control of large-scale qubit systems, including, for example, microsecond-latency feedback and nanosecond-precision timing of gigahertz signals-demands that far exceed the capabilities of conventional real-time systems. The rapidly evolving and highly diverse nature of quantum control necessitates the development of specialized hardware accelerators. While a few custom real-time systems have been developed to meet the tight timing constraints of specific quantum platforms, they face major challenges in scaling and adapting to increasingly complex control demands-largely due to fragmented toolchains and limited support for design automation. To address these limitations, we present RISC-Q---an open-source flexible generator for Quantum Control System-on-Chip (QCSoC) designs, featuring a programming interface compatible with the RISC-V ecosystem. Developed using SpinalHDL, RISC-Q enables efficient automation of highly parameterized and modular QCSoC architectures, supporting agile and iterative development to meet the evolving demands of quantum control. We demonstrate that RISC-Q can replicate the performance of existing QCSoCs with significantly reduced development effort, facilitating efficient exploration of the hardware-software co-design space for rapid prototyping and customization.
