Quantum Motion Integrates Silicon Spin Architecture with NVIDIA CUDA-Q Logical Compiler Stack
Quantum Motion has integrated its silicon spin architecture with NVIDIA CUDA-Q Logical, enabling automated quantum error correction-aware compilation. …
Silicon spin-qubit developer Quantum Motion has integrated its software pipeline with NVIDIA CUDA-Q Logical, an open-source logical orchestration and compilation layer within the CUDA-Q platform. The integration automates quantum error correction (QEC)-aware compilation, translating high-level logical algorithm primitives into hardware-level instructions mapped directly to Quantum Motion's silicon spin QPU topologies.
The compilation architecture specifically models Quantum Motion's looped pipeline architecture, which relies on electron shuttling—the physical translation of individual electron spins across the silicon substrate—to link processing nodes without dense physical wiring interconnects. By shuttling multiple qubits within localized physical loops, the hardware enables fast transversal two-qubit operations between surface code layers, turning standard two-dimensional (2D) planar surface code layouts into a three-dimensional (3D) virtual-z topology. The CUDA-Q Logical integration automates spatial placement by routing frequently interacting logical qubits into shared physical loops, replacing manual compilation estimates with Quantum Intermediate Representation (QIR) instruction output.

The automated compilation stack targets large-scale electronic structure calculations, providing end-to-end logical resource estimation for complex molecular systems like the iron-molybdenum cofactor (FeMoco). The workflow interfaces with Quantum Motion's ongoing algorithms research—including the QUICHE (QUantum Integrated CHEmistry) project alongside FACCTs and Riverlane—to establish automated pipelines from high-level computational chemistry software (ORCA) down to hardware-executable fault-tolerant logical circuits.
