The first on-site commercial quantum computer cluster has been launched at the Oak Ridge Leadership Computing Facility (OLCF) by Quantum Brilliance and the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL). The installation is a big step toward combining classical and quantum high-performance computing (HPC) to spur industrial advancement and scientific research.
Building the Future of Hybrid Computing
“By hosting a Quantum Brilliance system on site, we’ll be maturing the real mechanics of hybrid computing — co‑scheduling, end‑to‑end performance tuning, data and workflow orchestration, workforce development and more” said Ashley Barker, OLCF Program Director at ORNL. “Leveraging the potential power of quantum computing in a hybrid ecosystem is important to the nation and aligns with ORNL’s mission of boosting innovation, energy, competitiveness, and national security.”
Quantum computers work using qubits that take advantage of quantum superposition, as opposed to conventional supercomputers like ORNL’s Frontier, which only use classical binary bits. This characteristic makes it possible to solve issues in data-intensive domains like chemistry and physics in novel ways. In order to expedite this study, ORNL published a framework in Future Generation Computer Systems, laying the foundation for quantum-classical integration already.
A Room-Temperature Breakthrough
Quantum Brilliance creates room-temperature quantum processors based on diamond. This is in stark contrast to the majority of quantum systems, which require large-scale laser-vacuum setups or cryogenic cooling to maintain the stability of qubits.
“Diamond is extremely hard, so even at room temperature and atmospheric pressure, there isn’t sufficient thermal energy to generate the vibrations that would typically disrupt qubit coherence,” explained Andreas Sawadsky, Quantum Brilliance’s Technology and Innovation Manager. “This intrinsic stability allows our QPUs to function without the complexity and cost of cryogenics, laser and vacuum systems. This allowed us to engineer a revolutionary QPU solution that operates efficiently at room temperature while dramatically reducing size, weight and power consumption.”
Three Quantum Development Kits (QDKs) with six qubits apiece, each with parallelized quantum processing units (QPUs), are now part of the ORNL testbed. The system will be used by researchers to investigate hybrid techniques and applications in fields including machine learning and computational chemistry.
Toward Scalable Quantum-HPC Integration
Quantum Brilliance CEO Mark Luo described the collaboration as “a milestone for the future of quantum computing,” underscoring the vision of integrating GPU-sized quantum processors directly into world-class HPC systems.
“This is about so much more than just hardware,” Luo said. “It is about building a future where quantum and classical systems collaborate on an unprecedented scale.”
Chief Technology Officer Dr. Marcus Doherty added that ORNL’s experiments with the QDKs will help design architectures where hundreds of quantum processors operate in parallel with classical supercomputers, much like GPUs do today.
Global Mission and Impact
Quantum Brilliance, which has offices in Germany and Australia, wants to make quantum technology scalable and widely used by integrating quantum processors into both commonplace gadgets and supercomputing centers. With global alliances in Asia Pacific, Europe, and North America, the business is establishing itself as a pioneer in hybrid quantum-classical computing.
ORNL and Quantum Brilliance are establishing the groundwork for a new era of computing, where quantum accelerators will be just as crucial as GPUs in addressing the most difficult scientific and industrial problems, by proving that room-temperature quantum processors are feasible in a top-tier HPC testbed.
