Quantum Computing Material Finding Tool Unveiled by UCC scientists
Updated June 02, 2025
Researchers at University College Cork (UCC) in Ireland have created a novel tool to pinpoint next-generation materials crucial for large-scale, fault-tolerant quantum computing. This breakthrough offers a definitive method to assess a material’s effectiveness in specific quantum computing microchips.
the findings,published in Science,stem from an international collaboration involving theoretical work from Prof. Dung-Hai Lee at the University of California, Berkeley, and material synthesis from professors Sheng Ran and Johnpierre Paglione at Washington University in St. Louis and the University of Maryland, respectively.
Using specialized equipment, the davis Group at UCC determined that Uranium ditelluride (UTe2), a known superconductor, possesses the characteristics of an intrinsic topological superconductor. Topological superconductors host unique quantum particles called Majorana fermions on their surface. These particles could perhaps store quantum information stably, resisting disturbances that plague current quantum computers. Physicists have sought an intrinsic topological superconductor for decades.
Since its discovery in 2019, UTe2 has been a promising candidate. Now, this new research definitively evaluates its suitability. Joe Carroll, a PhD researcher at the Davis Group, and Kuanysh Zhussupbekov, a Marie Curie postdoctoral fellow, led experiments using a scanning tunneling microscope (STM) operating in a new mode developed by Séamus Davis, professor of quantum physics at UCC.
The experiments, conducted with the “Andreev” STM—available only in Davis’ labs in Cork, Oxford University, and Cornell University—confirmed UTe2 as an intrinsic topological superconductor, albeit not precisely the type initially sought. Nevertheless, the experiment itself marks a significant advance.
“Traditionally researchers have searched for topological superconductors by taking measurements using metallic probes… What’s new about our technique is that we use another superconductor to probe the surface of ute2… leaving behind only the Majorana fermions,” Carroll said.
Carroll added that this technique enables scientists to directly assess other materials for topological quantum computing applications. Quantum computers can solve complex mathematical problems in seconds, a task that would take conventional computers years. Governments and companies globally are racing to develop quantum processors with increasing quantum bits. Though, the instability of quantum calculations hinders progress.
Earlier this year, Microsoft unveiled the Majorana 1, which they call “the world’s first Quantum processing Unit (QPU) powered by a Topological Core.” Microsoft uses synthetic topological superconductors based on engineered stacks of conventional materials to achieve this.
The Davis Group’s work suggests that single materials could replace these complex circuits, potentially boosting quantum processor efficiency and enabling more qubits on a single chip, thus accelerating the progress of next-generation quantum computing.
What’s next
This new tool promises to accelerate the discovery of materials suitable for fault-tolerant quantum computers, potentially leading to more powerful and stable quantum processors in the future.
