NVIDIA Ising

# NVIDIA Ising 

NVIDIA Ising is a model family, training framework, and cookbook for building and deploying AI for [quantum computing](https://www.nvidia.com/en-us/glossary/quantum-computing/). Leveraging NVIDIA Ising enables quantum computing experts to get the full value of state-of-the-art artificial intelligence technology without requiring machine learning domain expertise. It solves existential blockers and scales useful quantum computing with the best classical computing has to offer.

## NVIDIA Ising Models

The NVIDIA Ising model family gives quantum computer builders, operators, and developers the AI tools required to scale devices to fault tolerance. Key challenges on that path include calibration and quantum error correction.   
  
The new Ising vision language model for quantum calibration can be leveraged in an agentic workflow to automate quantum processor bring-up and retune calibration workflows.   
  
[Quantum error correction](https://www.nvidia.com/en-us/glossary/quantum-error-correction/) decoders need to be low latency while improving the logical error rate (LER) of the quantum processor they are connected to. Until now, machine learning pre-decoders capable of simultaneously reducing end-to-end latency, improving the LER, and scaling across both space and time to enable efficient lattice surgery operations have not been available. 3D CNN model architectures are key to supporting this capability, and NVIDIA Ising includes a fast, accurate model for SurfaceCode and ColorCode with off-the-shelf noise models.

### Ising Calibration 1.5

## NVIDIA Ising Calibration and Ising Decoding

NVIDIA Ising Decoding includes a training pipeline for decoder models so you can train your own decoders and custom tailor them to their quantum computer noise models for the best performance. Examples are included for real-time decoding with the models, along with scripts to quantize.   
  
NVIDIA Ising Calibration offers an agentic workflow to enable out-of-the-box ease of use with Ising Calibration 1.5. Learn how to deploy the model with an agent or integrate with your QPU. Use examples for fine-tuning the models with your own data and the QCalEval benchmark and data to test model effectiveness.
