Xanadu and Oak Ridge National Laboratory push the boundaries of large-scale quantum programming on the Frontier supercomputer
Rhea-AI Summary
Xanadu (NASDAQ: XNDU) and Oak Ridge National Laboratory enabled PennyLane to run on the Frontier exascale supercomputer as of April 29, 2026. PennyLane's Lightning simulator now supports MPI-based multi-node execution on Frontier's AMD CPUs and GPUs, and Xanadu ran a hands-on workshop for OLCF users.
The integration aims to let researchers simulate larger quantum programs, benchmark algorithms, and identify performance bottlenecks ahead of fault-tolerant quantum computing.

Users of Frontier and the broader Oak Ridge Leadership Facility (OLCF) community can now utilize PennyLane to write and execute quantum programs directly on the Frontier supercomputer using PennyLane's high-performance Lightning simulator. This collaboration pushes the limits of quantum computing simulation by merging Frontier's exascale capabilities, powered by AMD's CPUs and GPUs, with PennyLane's accessible programming interface.
In order to prototype, test, and validate larger quantum programs and algorithms, researchers often need supercomputing resources to simulate a large number of qubits. With the ability to run PennyLane on Frontier, researchers can now explore complex problems and identify performance bottlenecks that are not present within smaller simulations. Researchers have a new, powerful set of tools to advance the field of quantum applications development, with fault-tolerant quantum computing on the horizon.
Xanadu has further advanced this work by integrating Message Passing Interface (MPI) with Lightning. MPI introduces the ability to communicate across multiple computational nodes and is a foundational tool for massively-parallelized classical high-performance computing. This integrated feature enables users to cut down on total runtimes and explore novel approaches for distributed computation by coupling Lightning with MPI for quantum simulation. Researchers are now able to easily leverage world-class parallel computing capabilities of AMD-powered hardware at the Frontier supercomputing facility for their quantum computing research.
Xanadu also supported the OLCF community through a comprehensive hands-on workshop. The goal of this workshop was to provide participants with the knowledge to start using PennyLane for quantum programming. In addition to general onboarding, the workshop also taught how PennyLane's high-performance capabilities could be leveraged with the supercomputing capabilities of Frontier.
"We're thrilled that PennyLane is now ready for researchers using Frontier to push the limits of quantum computing simulation. PennyLane was designed to provide an accessible user interface, support hybrid classical-quantum programs, and integrate with high-performance simulators - all features that complement Frontier's classical supercomputer," said Dr. Christian Weedbrook, Founder and Chief Executive Officer of Xanadu.
"By leveraging the exascale performance of Frontier's AMD-powered systems with Xanadu's accessible PennyLane software framework, we are enabling the OLCF user community to simulate quantum programs at scale. This capability supports benchmarking of algorithms, investigation of hardware constraints, and preparation for future fault-tolerant quantum applications," said Michael Sandoval, a high-performance engineer at OLCF and organizer of the PennyLane on Frontier workshop.
As the field of quantum computing continues to accelerate, collaborations between industry and national laboratories are poised to unlock new discoveries in quantum computing and beyond. Xanadu and ORNL stand ready to support the world-class researchers pushing the limits of the field.
