Q-CTRL, NVIDIA, and OQC Collaborate to Accelerate Quantum Error Suppression
Mohamed Abdel-Kareem2025-03-20T21:05:12-07:00Q-CTRL, in partnership with NVIDIA and Oxford Quantum Circuits (OQC), has demonstrated a 500,000x reduction in classical compute costs for quantum error suppression tasks by leveraging NVIDIA GPUs and accelerated libraries. The work focuses on optimizing the layout ranking process, a computationally intensive step in mapping abstract quantum circuits to physical qubits. This process involves evaluating potential mappings while accounting for qubit connectivity constraints and hardware performance variations, which becomes exponentially complex as qubit counts scale. The team developed GPU-accelerated implementations of the layout ranking process using NVIDIA’s RAPIDS and cuDF libraries. These implementations employ two levels of parallelism: (1) layout-level parallelism, where multiple circuit layouts are [...]
