Quantum Motion Integrates Silicon Spin Architecture with NVIDIA CUDA-Q Logical Compiler Stack

Quantum Motion Integrates Silicon Spin Architecture with NVIDIA CUDA-Q Logical Compiler Stack Quantum Motion’s looped pipeline architecture realises surface code stacking using shuttling multiple qubits within a single loop. Intra-loop interactions are fast, allowing for transversal operations between surface code layers. 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.
