quantum-centric supercomputing technical

"the industry's first published quantum‑centric supercomputing reference architecture"

A computing approach that puts a quantum processor at the center of a high-performance system and pairs it with conventional supercomputing hardware to solve certain problems much faster than ordinary computers. Think of it as fitting a new kind of engine into a race car: for some specific tracks—like complex optimization, materials design, or certain simulations—the new engine can offer a big speed or capability advantage, but it requires heavy R&D, specialized infrastructure, and carries technical and commercial uncertainty that investors should weigh.

quantum processors technical

"The architecture shows how quantum processors (QPUs) can work alongside GPUs and CPUs"

Quantum processors are specialized computer chips that use the rules of quantum physics to process information with quantum bits (qubits), which can represent many possibilities at once rather than just 0 or 1. For investors, they matter because they promise drastically faster solutions for certain tasks—like searching databases, simulating materials, or optimizing complex systems—meaning companies that master or apply them could gain major technological and market advantages, but development is capital-intensive and risky.

gpus technical

"quantum processors (QPUs) can work alongside GPUs and CPUs—across on‑premises systems"

GPUs are specialized computer chips originally designed to draw images on screens but now widely used to speed up tasks like artificial intelligence, scientific calculations, and data analysis. For investors, GPU demand is a signal about where computing power is being deployed — rising GPU sales can boost makers of chips and the datacenters that use them, influence supply chains and prices, and indicate which companies have a performance edge, much like a restaurant gaining an advantage by hiring many fast, skilled cooks.

cpus technical

"quantum processors (QPUs) can work alongside GPUs and CPUs—across on‑premises systems"

CPUs are the central processing units — the “brains” of computers, servers and many electronic devices that carry out instructions and run software. Investors care because CPU performance, availability and cost affect a company’s product capabilities, operating expenses and supply chain resilience the way an engine’s power and reliability shape a car maker’s lineup and manufacturing costs.

high-performance computing technical

"The future lies in quantum-centric supercomputing, where quantum processors work together with classical high-performance computing"

A cluster of very powerful computers, special chips and fast networks designed to tackle huge, complex calculations far faster than a normal PC — like replacing a single delivery van with a synchronized fleet to move a city’s worth of packages. For investors, high-performance computing matters because it enables faster product development, more accurate simulations and data analysis, and new revenue streams for hardware, software and services, making firms that supply or use it potentially more competitive and scalable.

orchestration technical

"Integrated orchestration and open software frameworks, including Qiskit, allow developers"

Orchestration is the coordinated management of multiple tasks, systems or teams so they work together smoothly, like a conductor ensuring each instrument plays at the right time. For investors, orchestration matters because it improves efficiency, speeds up delivery, reduces errors and operational costs, and makes scaling or changing business processes less risky—factors that can directly affect a company’s profitability and reliability.

many-body quantum chaos medical

"published methods in Nature Physics to accurately simulate many-body quantum chaos systems"

Many-body quantum chaos describes how unpredictability and rapid information spreading can emerge when a large number of quantum particles interact strongly, like a crowded dance floor where each dancer’s motion quickly affects everyone else. For investors, it matters because this behavior sets practical limits and opportunities for quantum technologies—affecting device stability, error rates, information security and how well quantum computers or sensors will perform in the real world.

closed loop data exchange technical

"through closed loop data exchange between a co-located IBM Quantum Heron processor"

A closed loop data exchange is an automated, two-way flow of information between systems or organizations that not only sends data but also confirms receipt, applies updates, and returns results so the whole process completes and corrects itself. Like a thermostat that senses temperature, adjusts heating, and reports the new reading, it improves accuracy, speeds decisions, reduces errors and regulatory risks, and can materially affect costs and reliability—key factors investors watch when assessing operational strength.

• New reference architecture outlines a practical, scalable path for combining quantum and classical computing
• Scientific breakthroughs in chemistry, materials science, and molecular simulation are pushing beyond the limit of classical computing driven through quantum-centric approach
• IBM's architecture brings quantum and classical computing together through open software and coordinated workflows

YORKTOWN HEIGHTS, N.Y., March 12, 2026 /PRNewswire/ -- IBM (NYSE: IBM) today unveiled the industry's first published quantum‑centric supercomputing reference architecture, a new blueprint for integrating quantum computing into modern supercomputing environments. The architecture shows how quantum processors (QPUs) can work alongside GPUs and CPUs—across on‑premises systems, research centers, and the cloud—in order to tackle scientific challenges that no single computing approach can solve on its own.

Designed for today's workloads and built to evolve over time, the architecture brings quantum and classical systems together into a unified computing environment. It combines quantum hardware with powerful classical infrastructure, including CPU and GPU clusters, high‑speed networking, and shared storage, to support computationally intensive workloads and algorithms research.

On top of this foundation, IBM's approach enables coordinated workflows that span quantum and classical computing. Integrated orchestration and open software frameworks, including Qiskit, allow developers and scientists to access quantum capabilities through familiar tools and workflows—making it easier to apply quantum computing to problems in areas such as chemistry, materials science, and optimization.

"More than four decades ago, Richard Feynman envisioned computers that could simulate quantum physics," said Jay Gambetta, Director of IBM Research and IBM Fellow. "At IBM, we've spent years turning that vision into reality. Today's quantum processors are beginning to tackle the hardest parts of scientific problems—those governed by quantum mechanics in chemistry. The future lies in quantum-centric supercomputing, where quantum processors work together with classical high-performance computing to solve problems that were previously out of reach. IBM is building the technology and systems that brings this future of computing into reality today."

Scientists are already using IBM's quantum-centric architecture to deliver accurate results for real experiments. Recent results represent some of the strongest evidence yet that quantum computers combined with classical computing workflows can be used to accelerate scientific discovery:

• Researchers from IBM, the University of Manchester, Oxford University, ETH Zurich, EPFL, and the University of Regensburg created a first‑of‑its‑kind half‑Möbius molecule, verifying its unusual electronic structure with a quantum-centric supercomputer published in Science.
• Cleveland Clinic simulated a 303‑atom tryptophan‑cage mini‑protein, one of the largest molecular models ever executed on a quantum-centric supercomputer.
• A team from IBM, RIKEN, and the University of Chicago uncovered the lowest‑energy state of engineered quantum systems, outperforming state-of-the-art classical‑only approaches.
• RIKEN and IBM scientists achieved one of the largest quantum simulations of iron‑sulfur clusters, a fundamental molecule in biology and chemistry, through closed loop data exchange between a co-located IBM Quantum Heron processor and all 152,064 classical compute nodes of RIKEN's Fugaku supercomputer.
• Algorithmiq, Trinity College Dublin, and IBM collaborators published methods in Nature Physics to accurately simulate many-body quantum chaos systems, such as collections of atoms and electrons, using classical compute resources for noise mitigation.

These results confirm the ability of IBM's quantum computers to deliver value to scientific problems.

As new quantum‑centric algorithms emerge, IBM's global ecosystem of clients and partners will continually evolve this architecture to support sophisticated resources, networks and software capabilities. For example, IBM and Rensselaer Polytechnic Institute are improving how workflows can be seamlessly scheduled and orchestrated across quantum and high-performance computing resources. Deploying new algorithms on top of this maturing architecture will drive the next wave of applications in chemistry, materials science, optimization, and beyond, poising them to scale exponentially.
