NVIDIA launches cudaq-realtime for microsecond-latency quantum feedback

cudaq-realtime is a critical bridge for the hybrid quantum-classical era, moving beyond simple acceleration to real-time closed-loop control. Microsecond-latency callbacks enable real-time QEC decoding, a mandatory requirement for scaling quantum computers to practical use. Persistent CUDA kernels bypass the CPU to allow FPGAs and GPUs to communicate directly via NVQLink and DOCA GPUNetIO. Ecosystem support from Dell, Qblox, and Quantum Machines validates NVIDIA's ambition to become the "operating system" for hybrid quantum data centers. The platform's optimization for Variational Quantum Algorithms (VQA) targets the most promising path toward near-term commercial quantum value.
