4 terms

exascale technical

"This collaboration pushes the limits of quantum computing simulation by merging Frontier's exascale capabilities"

A computing system described as exascale can perform at least one quintillion (10^18) calculations per second, enabling extremely large simulations, data analysis, and AI workloads. For investors, exascale matters because it can unlock faster drug discovery, weather forecasting, financial modeling and AI services—offering companies a competitive edge, higher revenue potential or heavy capital costs, depending on who builds, supplies or uses this rare, powerful infrastructure.

message passing interface (mpi) technical

"Xanadu has further advanced this work by integrating Message Passing Interface (MPI) with Lightning."

Message Passing Interface (MPI) is a standardized way for separate programs or computers to exchange data and coordinate work, commonly used in high-performance and distributed computing. It matters to investors because efficient MPI lets organizations run large calculations faster and more cheaply—like workers passing buckets along an assembly line—so research, simulations, and cloud services can scale, lowering costs and improving competitive performance.

fault-tolerant quantum computing technical

"with fault-tolerant quantum computing on the horizon."

Fault-tolerant quantum computing is the ability of a quantum computer to keep producing correct results even when its basic parts make mistakes, by detecting and fixing errors and using redundancy so the machine continues to work reliably. For investors, it matters because fault tolerance is the key to scaling quantum machines from experimental demos into practical, revenue-generating systems—think of it like having backups and automatic repairs that make a prototype road-ready and lower the technology’s commercial and technical risk.

hybrid classical-quantum programs technical

"PennyLane was designed to provide an accessible user interface, support hybrid classical-quantum programs"

Hybrid classical-quantum programs are software systems that split work between ordinary computers and quantum processors, using the strengths of each like a team where a calculator handles routine tasks and a specialized tool tackles the hardest parts. For investors, they matter because they are the practical route to using quantum advantage in real products: they can unlock faster problem solving or new capabilities while relying on existing infrastructure, affecting hardware demand, software services, and competitive positioning.

TORONTO, April 29, 2026 /PRNewswire/ - Xanadu Quantum Technologies Ltd. ("Xanadu") (NASDAQ: XNDU) (TSX: XNDU), a leading photonic quantum computing company, and the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), one of the largest scientific research centers in the United States, have collaborated to enable cutting-edge research in quantum computing by leveraging Xanadu's open-source quantum software library, PennyLane, on the Frontier supercomputer, one of the most advanced computing systems in the world.

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.
