Physicists just found the ‘ghost’ of superconductivity
Physicists have found striking evidence for an unusual form of superconducting behavior in uranium ditelluride, where electron pairs organize into rippling patterns called pair density waves. Even more surprisingly, these patterns appear to survive after ordinary superconductivity disappears, suggesting that the electron pairs responsible for superconductivity may begin forming before the material actually becomes superconducting.

This new qubit could be 100 times less error-prone in superfluid quantum computer breakthrough
A proposed qubit made with superfluid helium could cut quantum computing error rates by around 100 times by shielding quantum information from common forms of electromagnetic noise. If experiments confirm the predictions, the technology could eventually work alongside today’s superconducting qubits or serve as a new kind of quantum memory.
CERN has begun disconnecting the Large Hadron Collider
CERN has started replacing some of the Large Hadron Collider’s most important magnets as part of its High-Luminosity upgrade. The new superconducting magnets will produce fields about 40% stronger, allowing particle beams to be squeezed more tightly before they collide. That should create far more collisions for the ATLAS and CMS experiments to analyze, giving physicists a much larger window into the fundamental workings of the universe.

Scientists discover two superconducting states hiding as one
Scientists have uncovered hidden complexity inside two ultrathin superconductors that seemed much simpler than they really are. Niobium diselenide and tantalum disulfide appeared to have a single superconducting state, but highly sensitive measurements revealed that each actually contains two strongly interacting states working so closely together that they masquerade as one.

Scientists twisted a mysterious superconductor and got a shocking result
A decades-old superconducting mystery just took a surprising turn. Strontium ruthenate, a material that conducts electricity with zero resistance at low temperatures, has long puzzled scientists with hints of an exotic, complex superconducting state. But by carefully twisting and distorting ultra-thin crystals, researchers found something unexpected: the material barely reacted at all. This challenges years of assumptions and suggests its behavior may be far simpler—or far stranger—than previously thought.
Scientists found a way to cool quantum computers using noise
Quantum computers need extreme cold to work, but the very systems that keep them cold also create noise that can destroy fragile quantum information. Scientists in Sweden have now flipped that problem on its head by building a tiny quantum refrigerator that actually uses noise to drive cooling instead of fighting it. By carefully steering heat at unimaginably small scales, the device can act as a refrigerator, heat engine, or energy amplifier inside quantum circuits.
A hidden magnetic order could unlock superconductivity
Physicists have discovered that hidden magnetic order plays a key role in the pseudogap, a puzzling state of matter that appears just before certain materials become superconductors. Using an ultra-cold quantum simulator, the team found that even when magnetism seems disrupted, subtle and universal magnetic patterns persist beneath the surface. These patterns closely track the temperature at which the pseudogap forms, suggesting magnetism may help set the stage for superconductivity.
Superconductors, an opportunity for science and society
Superconductive technologies have long been central to particle physics, but they have also repeatedly moved beyond the laboratory, most notably with the emergence of magnetic resonance imaging scanners (MRI), demonstrating how breakthroughs in fundamental research can benefit society. Today, as global energy, climate and healthcare pressures grow, the conversation is shifting from “What can science give to society?” to “How can science and industry jointly develop technologies that benefit society while advancing research?” The event “Catalysing Impact – Superconductivity for Global Challenges” held at CERN in December was aimed precisely at answering this question. The workshop brought together leading researchers, industry representatives, investors and policymakers to explore how collaboration on superconducting technologies can advance particle physics while addressing some of the world’s most pressing societal challenges. The event sought to bridge fundamental research with real-world deployment and to accelerate collaborative pathways. Across keynotes, panels and round tables, participants examined both the current technological landscape and the opportunities ahead. Introducing the discussions, Frédérick Bordry, Chief Technology Officer of the Gauss Fusion company and former CERN Director for Accelerator and Technology, noted that “Superconductivity has become the silent engine of discovery science.” While the research community needs more capable and more resilient superconductors for the next generation of experiments, they also have significant potential for societal applications. Beyond their role in collider magnets, high-temperature superconductors (HTS) now promise lossless power transmission, compact fusion magnets, efficient renewable systems and new capabilities in healthcare, transport, computing and quantum technologies - all aligned with SDG-17’s emphasis on partnership-driven innovation. Participants also stressed that major hurdles remain. Global competition is accelerating, and Europe must act quickly to secure technological and economic leadership. Doing so will require coordinated investment and supportive policies, including stronger risk capital investment and mechanisms to bridge the gap between laboratory innovation and industrial deployment. The summit set in motion several concrete follow-up priorities, including aligning R&D roadmaps with societal goals and the UN Sustainable Development Goals; making it easier for public–private consortia to build demonstrators that serve both industry and research needs; and advancing investment pathways that better connect research institutions, governments and the private sector.

A new superconductor breaks rules physicists thought were fixed
A shiny gray crystal called platinum-bismuth-two hides an electronic world unlike anything scientists have seen before. Researchers discovered that only the crystal’s outer surfaces become superconducting—allowing electrons to flow with zero resistance—while the interior remains ordinary metal. Even stranger, the electrons on the surface pair up in a highly unusual pattern that breaks all known rules of superconductivity.
