Key Terms

quantum-centric supercomputing, neutron scattering, quantum processors, qubit simulation

4 terms

quantum-centric supercomputing technical

"High simulation accuracy is enabled by quantum-centric supercomputing workflows..."

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.

neutron scattering medical

"results that match neutron scattering experiments, marking a significant step..."

Neutron scattering is a laboratory technique that uses a beam of neutrons to reveal the internal structure and movements of materials or biological molecules, similar to shining a special light through an object to see how it’s built. For investors, it matters because the detailed insights it provides can prove how well a material, drug, battery or other technology will perform, reduce development risk, support patents and help forecast costs and timelines.

quantum processors technical

"demonstrates that quantum processors can now capture key dynamical properties..."

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.

qubit simulation technical

"the most impressive match I've seen between experimental data and qubit simulation..."

Qubit simulation is the use of software and classical computers to imitate how quantum bits (qubits) behave and how quantum programs would run, much like a flight simulator mimics an aircraft to test pilots and procedures without leaving the ground. For investors, it matters because these simulations help predict performance, identify technical hurdles, estimate timelines and costs for real quantum hardware, and de-risk product development or commercial offerings in the quantum computing sector.

YORKTOWN HEIGHTS, N.Y., March 26, 2026 /PRNewswire/ -- IBM (NYSE: IBM) today announced new results that its quantum computer can simulate real magnetic materials with results that match neutron scattering experiments, marking a significant step towards using quantum computers as reliable tools for scientific discovery. The work, reported in a pre-print, was conducted by scientists from the U.S. Department of Energy-funded Quantum Science Center at Oak Ridge National Laboratory, Purdue University, University of Illinois Urbana-Champaign, Los Alamos National Laboratory, the University of Tennessee and IBM.

The ability to design new materials—such as better superconductors, more efficient batteries, or novel drugs—depends on understanding quantum behavior that is often challenging for classical methods to model. While quantum computers are expected to address this challenge, it has remained unclear whether today's processors could deliver quantitatively reliable simulations of real materials. These results show that current quantum hardware, combined with new algorithms and quantum-centric supercomputing workflows, can already simulate properties of materials, which in general, can be difficult to predict using classical methods alone.

"There is so much neutron scattering data on magnetic materials that we don't fully understand because of the limitations of approximate classical methods," said Arnab Banerjee, assistant professor of Physics and Astronomy at Purdue University. "Using a quantum computer for better understanding these simulations and comparing experimental data has been a decade-long dream of mine, and I'm thrilled that we have now demonstrated for the first time that we can do that."

The Experiment

Scientists have long used neutron sources to reveal the quantum properties of materials by measuring how incident neutrons exchange energy and momentum with spins in the material. In this study, the team focused on the well-characterized magnetic crystal KCuF₃ and directly compared neutron scattering measurements with simulations on a quantum computer. The agreement between experiment and simulation demonstrates that quantum processors can now capture key dynamical properties of real materials. "This is the most impressive match I've seen between experimental data and qubit simulation, and it definitely raises the bar for what can be expected from quantum computers," said Allen Scheie, condensed matter physicist at Los Alamos National Laboratory. "I am extremely excited for what this means for science."

These results begin to establish quantum computers as reliable computational tools for material simulation. "Quantum simulations of realistic models for materials and their experimental characterization is a major demonstration of the impact quantum computing can have on scientific discovery workflows," said Travis Humble, director of the Quantum Science Center at Oak Ridge National Lab.

The study also highlights how improvements in the scale and quality of quantum processors were crucial for the simulation accuracy achieved. "These results were really enabled by the two-qubit error rates that we can now access on our quantum processors," said Abhinav Kandala, principal research scientist at IBM. "We expect further improvements in error rates and extensions to higher dimensions to enable predictions of material properties that are challenging for classical methods alone." Leveraging the programmability of a universal quantum processor, the team has already extended the approach beyond KCuF₃ to simulate material classes with more complex interactions.

Building Toward the Quantum Era

This experiment is part of a broader shift in how quantum computers are being applied toward scientific problems defined by laboratories. Recent results include the first quantum simulation of a never-before-seen in nature half-Möbius molecule and a large-scale protein simulation with Cleveland Clinic. Across chemistry, materials science, and molecular biology, quantum simulation is beginning to engage with problems that matter to scientists.

The quantum-centric supercomputing approach demonstrated here is designed to deliver scientific and commercial value by combining today's quantum hardware with classical computing in workflows that make productive use of both.
