Exascale Meets Quantum: Xanadu and Oak Ridge National Laboratory Push the Limits of Simulation on the World’s Fastest Supercomputer
A historic alliance will advance quantum computing using the Frontier supercomputer and Xanadu Quantum Technologies Ltd.’s open-source program PennyLane. High-performance computing is transformed by the cooperation, which lets researchers run large-scale quantum simulations on one of the most powerful computational systems ever created.
Bridging Exascale and Quantum Programming
PennyLane, an open-source software framework for quantum machine learning, chemistry, and general quantum computing, may be used directly on Frontier’s hardware by the Oak Ridge Leadership Computing Facility (OLCF) community, which is the foundation of this partnership. Researchers may now create and run quantum algorithms that use Frontier’s enormous exascale capability by utilizing PennyLane’s high-performance Lightning simulator.
AMD’s cutting-edge CPUs and GPUs power Frontier, which is well known for its unmatched computing capability. PennyLane’s integration makes it possible to combine these traditional exascale capabilities with easily accessible quantum programming interfaces. This environment is essential for researchers who must develop, test, and validate complex quantum algorithms that need the simulation of a huge number of qubits—a task that is beyond the capability of traditional local hardware.

Overcoming Obstacles with Parallelized Simulation
The integration of the Message Passing Interface (MPI) with the Lightning simulator is one of the most important technological developments as a result of this collaboration. To enable massively parallelized activities, MPI is a fundamental technology in conventional high-performance computing.
A new age of distributed quantum computation has been made possible by Xanadu’s combination of Lightning and MPI. Users are able to:
- Significantly cut down on complicated simulations’ overall runtimes.
- Examine new methods for quantum programming that are distributed.
- Utilize all of the AMD-powered hardware’s parallel computing capacity at the Frontier site.
High-performance engineer Michael Sandoval of OLCF claims that this scaling capability is essential for algorithm benchmarking and hardware constraint research. Scientists can use it as a sandbox to find performance problems that only show up when simulations are extended to enormous sizes and were previously hard to find in smaller-scale settings.

Preparing for a Fault-Tolerant Future
Preparing the scientific community for the emergence of fault-tolerant quantum computing is the ultimate objective of this partnership. Even while real fault-tolerant technology is still a ways off, researchers can create the “software DNA” needed for future innovations by simulating these systems at scale now.
“We’re excited that researchers can now use Frontier to push the boundaries of quantum computing simulation with PennyLane,” said Dr. Christian Weedbrook, CEO and founder of Xanadu. He underlined that PennyLane was an ideal addition to Frontier’s classical infrastructure because it was created especially to handle hybrid classical-quantum programming and interface with high-performance simulators.
Xanadu and ORNL held a thorough practical session to make sure the OLCF community could use these tools right away. At this session, researchers received both general PennyLane onboarding and specific training on optimizing Frontier’s supercomputing capabilities for their quantum applications.

About the Collaborators
Established in 2016, Xanadu Quantum Technologies is a prominent Canadian photonic quantum computing enterprise. As the first pure-play photonic quantum computing business to go public, the company recently achieved a significant milestone by going public under the ticker XNDU. Beyond hardware, Xanadu is a world leader in the creation of quantum software, maintaining the PennyLane framework and the Catalyst package, which facilitates effective just-in-time (JIT) compilation for hybrid workflows.
UT-Battelle manages Oak Ridge National Laboratory for the DOE Office of Science. ORNL, one of the largest US scientific research institutes, develops sustainable energy and worldwide security technologies. The OLCF at ORNL has top-notch technology, such as Frontier, to help scientists push the limits of science.
This collaboration between national laboratories and industry is a model for how classical exascale resources will support and stimulate the next wave of quantum discoveries as quantum computing technology continues to advance.
