# NVIDIA CUDA-QX

Quantum researchers and developers across a wide range of domains, from quantum error correction to hybrid solvers, use GPU programming to accelerate their applications. This demands highly optimized, domain-specific libraries. NVIDIA CUDA-QX, built on top of CUDA-Q™, is a collection of libraries and tools for accelerating research and development toward useful accelerated quantum supercomputing.

## CUDA-QX Libraries

CUDA-QX libraries are built on top of [CUDA-Q](https://developer.nvidia.com/cuda-q), NVIDIA’s open-source, hardware-agnostic platform for accelerated quantum supercomputing, and are also released open-source on GitHub. The CUDA-QX libraries provide optimized implementations of key quantum primitives—from quantum error correction to hybrid algorithms—enabling developers to easily leverage the CUDA-Q platform.

### CUDA-Q QEC

CUDA-Q QEC, which includes GPU-accelerated decoding primitives, Google’s stim stabilizer simulator, and extension points in CUDA-Q for custom decoders, is the foundational toolkit for any error correction researcher.

## Performance

### Single Syndrome Decoding Latency

### Batched Decoding Throughput

Belief Propagation-Ordered Statistics Decoding (BP-OSD) is one of the most promising approaches for scalable quantum error correction. CUDA-Q QEC accelerates BP-OSD with state-of-the-art latency and throughput, offering a 29–35x speedup over industry standard decoders for a single shot, as well as an additional speedup of up to 42x for high-throughput use cases where many syndromes need to be decoded at once.
