quantum computing technical

"It shows how quantum computers can directly contribute to understanding complex"

Quantum computing is a type of advanced technology that uses the principles of quantum physics to perform calculations much faster than traditional computers. It can process vast amounts of information simultaneously, potentially solving complex problems that are currently impossible or take too long with regular computers. For investors, this technology could lead to breakthroughs in areas like cryptography, data analysis, and optimization, impacting financial markets and security systems.

quantum-centric supercomputing technical

"real-world experimentation with 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.

quantum processing units (qpus) technical

"By integrating quantum processing units (QPUs), CPUs, and GPUs"

Specialized computer chips that use tiny quantum particles instead of ordinary bits to perform certain calculations in ways classical processors cannot; think of them as machines that can explore many possibilities at once rather than checking one path at a time. Investors care because QPUs could unlock faster solutions for problems like materials design, optimization, and cryptography, creating new markets and competitive advantage, but they also involve high development costs and uncertain commercial timelines.

scanning tunneling microscope technical

"The scanning tunneling microscope (STM) was invented at IBM in 1981"

A scanning tunneling microscope is a lab instrument that images and can manipulate individual atoms on a material’s surface by moving an extremely sharp probe nearby and measuring tiny electrical signals—like reading Braille at the atomic scale. Investors care because STM underpins development and quality control of advanced materials, nanoscale electronics and sensors; its use can speed research, create patentable innovations and improve manufacturing precision, all of which can influence future product competitiveness and company value.

atomic force microscopy technical

"Experiments with scanning tunneling and atomic force microscopy"

Atomic force microscopy is a laboratory technique that scans an ultra-fine probe across a surface to map its shape and mechanical or electrical properties at the scale of atoms — like feeling the bumps and textures of a surface with a microscopic fingertip. It matters to investors because AFM provides concrete evidence about material quality, nanoscale device performance and manufacturing consistency, information that can influence product prospects, patent strength and commercial risk assessments.

qubits technical

"Quantum computers are naturally well-suited for this problem because their building blocks – qubits –"

Qubits are the basic units of information in quantum computing, similar to how traditional computers use bits. Unlike regular bits that are either 0 or 1, qubits can represent both at the same time, allowing quantum computers to process complex problems much faster. This potential for unprecedented speed and power could transform industries, making qubits a key focus for investors interested in cutting-edge technology.

pseudo-jahn-teller effect technical

"reveAL the mechanism behind the formation of the unusual topology: a helical pseudo-Jahn-Teller effect"

A pseudo‑Jahn‑Teller effect is a phenomenon in molecules and solids where the arrangement of atoms shifts because two electronic states interact with the atoms’ motions, causing a stable structure to become distorted. Think of it like two nearby voices pushing on a hanging mobile until it tilts; that tilt changes how the material conducts electricity, absorbs light, or reacts chemically. Investors should care because this effect can determine a material’s performance and stability in technologies such as semiconductors, batteries, sensors and optoelectronic devices.

- Published today in Science, the discovery marks the creation and observation of the first molecule with a half-Möbius electronic topology.
- It shows how quantum computers can directly contribute to understanding complex molecular behavior.

YORKTOWN HEIGHTS, N.Y., March 5, 2026 /PRNewswire/ -- An international team of scientists from IBM (NYSE: IBM), The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any previously known — one whose electrons travel through its structure in a corkscrew-like pattern that fundamentally alters its chemical behavior. Published today in Science, it is the first experimental observation of a half-Möbius electronic topology in a single molecule.

To the scientists' knowledge, a molecule with such topology has never before been synthesized, observed, or even formally predicted. Understanding this molecule's behavior at the electronic structure level required something equally fundamental: a high fidelity quantum computing simulation.

The discovery advances science on two fronts. For chemistry, it demonstrates that electronic topology — the property governing how electrons move through a molecule — can be deliberately engineered, not merely found in nature. For quantum computing, it is a concrete demonstration of a quantum simulation doing what it was designed to do: representing quantum mechanical behavior directly, at the molecular scale, to produce scientific insight that would otherwise have remained out of reach. 

"First, we designed a molecule we thought could be created, then we built it, and then we validated it and its exotic properties with a quantum computer," said Alessandro Curioni, IBM Fellow, Vice President, Europe and Africa, and Director of IBM Research Zurich. "This is a leap towards the dream laid out by renowned physicist Richard Feynman decades ago to build a computer that can best simulate quantum physics and a demonstration where, as he said, 'There's plenty of room at the bottom.' The success of this research signals a step towards this vision, opening the door for new ways to explore our world and the matter within it."

A Never-Before-Seen Molecule

The molecule, with the formula C₁₃Cl₂, was assembled atom-by-atom at IBM from a custom precursor synthesized at Oxford University, with individual atoms removed one at a time using precisely calibrated voltage pulses under ultra-high vacuum at near-absolute-zero temperatures.

Experiments with scanning tunneling and atomic force microscopy, both techniques pioneered at IBM, combined with quantum computing to reveal an electronic configuration with no counterpart in chemistry's existing record: an electronic structure that undergoes a 90-degree twist with each circuit, requiring four complete loops to return to the starting phase.

This half-Möbius topology is qualitatively distinct from any previously known molecule and can be reversibly switched between clockwise-twisted, counterclockwise-twisted and untwisted states — demonstrating that electronic topology is not a property to be discovered, but one that can now be deliberately engineered under specific conditions.

A Disruptive Scientific Tool: Quantum-Centric Supercomputing

The scientists in this experiment created a molecule that had never existed. Now they had to figure out why it worked, a task which challenged conventional computers. The electrons within C₁₃Cl₂ interact in deeply entangled ways — each influencing all the others simultaneously. Modeling that behavior requires tracking every possible configuration of those interactions at once, requiring computational demands that grow exponentially and can quickly overwhelm classical machines.

Quantum computers are different by nature because they operate according to the same quantum mechanical laws that govern electrons in molecules, and they can represent these systems directly rather than approximate them. They "speak" the same fundamental language as the matter they are built to study and that distinction, once largely theoretical, can now contribute to concrete scientific results.

This capability offers tremendous potential for quantum computers to support real-world experimentation with quantum-centric supercomputing workflows. By integrating quantum processing units (QPUs), CPUs, and GPUs, quantum-centric supercomputing allows complex problems to be broken into parts that are orchestrated and solved according to each system's strengths — achieving what no single compute paradigm can deliver alone.

Utilizing an IBM quantum computer within such a workflow, the team found helical molecular orbitals for electron attachment, a fingerprint of the half-Möbius topology. Moreover, simulation via quantum computing helped reveal the mechanism behind the formation of the unusual topology: a helical pseudo-Jahn-Teller effect.

This achievement builds on IBM's long legacy in nanoscale science. The scanning tunneling microscope (STM) was invented at IBM in 1981, for which IBM scientists Gerd Binnig and Heinrich Rohrer were awarded the Nobel Prize in 1986. Its creation enabled researchers to image surfaces atom by atom. In 1989, IBM scientists developed the first reliable method for manipulating individual atoms. Over the past decades, the IBM team has extended these techniques to build and control increasingly exotic molecular structures.

RESEARCHER QUOTES

Dr. Igor Rončević, paper co-author, Lecturer in Computational and Theoretical Chemistry at Manchester University:
"Chemistry and solid-state physics advance by finding new ways to control matter. In the second half of the 20^th century, substituent effects were very popular. For example, researchers explored how the potency of a drug or the elasticity of a material changes if, for example, a methyl is replaced with chlorine. The turn of the century brought us spintronics, introducing electron spin as a new degree of freedom to play with, and transforming data storage. Today, our work shows that topology can also serve as a switchable degree of freedom, opening a new powerful route for controlling material properties.

"The non-trivial topology of this molecule, and the exotic behavior of many other systems, arises from interactions between their electrons. Simulating electrons with classical computers is very hard – a decade ago we could exactly model 16 electrons, and today we can go up to 18. Quantum computers are naturally well-suited for this problem because their building blocks – qubits – are quantum objects, which mirror electrons. Using IBM's quantum computer, we were able to explore 32 electrons. However, the most exciting part is this is just the start. Quantum hardware is advancing rapidly, and the future is quantum."

Dr. Harry Anderson, paper co-author, Professor of Chemistry at Oxford University:
"It is remarkable that the Lewis structure of C₁₃Cl₂ already indicates it is chiral, as confirmed by the experiment and quantum chemical calculations. It is also amazing that the enantiomers can be interconverted by applying voltage pulses from the probe tip."

Dr. Jascha Repp, paper co-author, Professor of Physics at the University of Regensburg:
"I'm really excited to be part of a project where quantum hardware does real science, not just demos. It's fascinating that a tiny molecule can have such a complex electronic structure that is challenging to simulate classically, and is so twisted and strange that it almost twists your mind."
