PROFILE

Cketcham2333

Developed core quantum error correction infrastructure for the NVIDIA/cudaqx repository, focusing on GPU-accelerated decoding and robust runtime stability. Leveraged C++ and CUDA to implement a CRTP-based decoder framework using CUDA graphs, enabling near-zero-CPU-overhead quantum-classical workloads. Enhanced streaming data processing with a sliding window decoder and introduced syndrome data persistence for quantum simulations, supporting advanced testing and validation. Improved developer experience by updating documentation and integrating Python-based pytest workflows. Addressed critical bugs in plugin lifecycle management and decoder configuration, reducing production risk. The work established a reliable, high-throughput foundation for quantum error correction and continuous integration in GPU environments.

February 2026 (NVIDIA/cudaqx): Delivered a GPU-driven Quantum Error Correction (QEC) decoder framework that enables near-zero-CPU-overhead decoding by leveraging CUDA graphs. Implemented a CRTP-based architecture with real-time CUDA-Q dispatch to maximize throughput and deterministic latency for quantum-classical workloads. Introduced a mock decoder for testing that uses a lookup table to validate the decoding infrastructure, and integrated the solution with CI/testing pipelines to ensure ongoing quality. The work establishes end-to-end GPU-accelerated decoding foundations and provides a strong baseline for performance-driven QEC workflows.
