Infleqtion said it used its qLDPC software with Nvidia's early-access CUDA-Q Logical software to build and validate an error-correction code encoding 18 logical qubits in 98 physical data qubits. The work reported a 5.4 physical-data-qubit-to-logical-qubit ratio and an 18.4% encoding rate. The integration covers code construction, logical ownership and compilation, not full physical syndrome extraction, noise modeling or decoder benchmarking.
