IonQ, ORNL, NVIDIA, and the University of Tennessee, Knoxville Show AI Method Reduces Quantum Optimization Trade Off

  • IonQ, Oak Ridge National Laboratory, NVIDIA, and the University of Tennessee, Knoxville, demonstrated that a trained generative AI model can directly write quantum optimization circuits to eliminate costly trial-and-error parameter tuning.
  • The research paper, presented at IEEE Quantum Week 2026 in Toronto, won a best paper award and details how the model replaces iterative tuning with fixed candidate evaluations.
  • The team trained a transformer model on near-optimal circuits generated by conventional methods, enabling it to sample ten candidates per subproblem and select the best score for global solution updates.
  • On a benchmark problem with 100 decision variables, the AI-generated approach doubled answer quality as subproblems grew while maintaining a constant runtime of approximately 28 seconds.
  • In contrast, the traditional state-of-the-art method saw circuit-finding time rise from 34 seconds on 4 qubits to over 11 minutes on 12 qubits.
  • All circuits in the study were simulated using the NVIDIA cuQuantum SDK on a single NVIDIA H200 GPU within the Defiant2 supercomputer system, ensuring a controlled comparison between workflows.
  • The study focuses on the distributed quantum approximate optimization algorithm (DQAOA) and its integration with generative AI to enable automatic circuit synthesis for increasingly complex problems.
  • Researchers plan to extend the framework to real-world scientific applications 8 scale it across larger high-performance computing systems.
  • The work was led by ORNL with co-authors from IonQ, NVIDIA, 8 UT, including Abhinav Rijal 8 Dr. Martin Roetteler.
  • IonQ's Superion quantum computers 8 previous systems have previously delivered 20x performance increases for partners including Amazon Web Services, AstraZeneca, 8 NVIDIA.
