Xanadu Quantum Technologies Ltd. has partnered with the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) to accelerate quantum computing research by enabling its open-source software library, PennyLane, on the Frontier supercomputer. Through this collaboration, researchers can now push the boundaries of quantum simulation by combining advanced software capabilities with one of the world’s most powerful computing systems.

With this development, users within the Oak Ridge Leadership Computing Facility (OLCF) community can directly write and execute quantum programs on Frontier using PennyLane’s high-performance Lightning simulator. As a result, the integration bridges the gap between quantum software development and exascale computing power. Moreover, Frontier’s AMD-powered CPUs and GPUs enhance the performance of PennyLane, allowing researchers to simulate quantum systems at unprecedented scale.

As quantum computing research evolves, scientists increasingly require high-performance computing resources to test and validate complex algorithms. Traditionally, limited simulation environments restricted the number of qubits researchers could effectively model. However, by enabling PennyLane on Frontier, Xanadu and ORNL now allow researchers to explore significantly larger quantum systems. Consequently, they can identify performance bottlenecks and refine algorithms more efficiently than before.

In addition, Xanadu has strengthened this initiative by integrating Message Passing Interface (MPI) with its Lightning simulator. This enhancement allows communication across multiple computational nodes, which is essential for large-scale, parallel processing. Therefore, researchers can reduce runtime and experiment with distributed quantum simulations more effectively. By combining MPI with Lightning, the platform unlocks new opportunities for leveraging Frontier’s massive parallel computing capabilities.

Furthermore, Xanadu actively supported the OLCF research community by hosting a hands-on workshop designed to onboard users to PennyLane. During the workshop, participants learned how to develop quantum programs and leverage the combined power of PennyLane and Frontier. This effort ensures that researchers not only gain access to advanced tools but also understand how to maximize their potential in real-world applications.

“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.

Ultimately, as quantum computing continues to advance, collaborations between technology companies and national laboratories are becoming increasingly critical. In this case, Xanadu and ORNL are not only expanding access to cutting-edge tools but also empowering researchers to accelerate innovation. By combining software accessibility with exascale computing performance, this partnership sets the stage for the next wave of breakthroughs in quantum computing and beyond.
