This research demonstrates a ten-fold reduction in runtime for detector error model sampling in distributed quantum computing simulations by leveraging NVIDIA CUDA-Q on GPUs. By accelerating the evaluation of logical failure rates across noisy interfaces, this approach enables more precise benchmarking of modular quantum architectures and informs critical decisions regarding error-correction overheads.

Welinq accelerates distributed quantum computing by leveraging NVIDIA CUDA-Q to speed up simulations using a detector error model (DEM).

Welinq is accelerating the development of distributed quantum computing by using NVIDIA CUDA-Q to speed up simulations of detector error models (DEMs). The research team captures how faults trigger error-detection signals and alter logical measurement outcomes within a DEM, then uses the open NVIDIA platform to accelerate sampling from this model. This advancement builds on a prior circuit-level study of fault-tolerant logical gates across noisy interfaces, reducing the computational cost of evaluating architectural performance. “Combined with decoding, these results constitute an important step for establishing the network requirements and error-correction overhead for reliable distributed quantum computation,” Welinq reports. Welinq accelerated simulations of distributed quantum computation by achieving a ten-fold reduction in sampling runtime using NVIDIA CUDA-Q, a platform for accelerating quantum circuit simulations. This speedup centers on detector error model (DEM)…
