A persistent quantum computing error finally explained
Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even when they have built-in defenses. For all their advanced hardware, superconducting quantum computers are vulnerable to errors caused by ionizing radiation from space or the environment. Radiation particles interfere with the chip substrate (the silicon base the processor is built on), which leads to the creation of rogue particles (quasiparticles) that disrupt the qubits, the basic units of quantum computers.
To protect against this, scientists developed a technique called gap engineering. This involves creating an energy barrier in the superconducting material of the qubits, making it harder for these particles to reach sensitive parts of the device.
However, it is not foolproof. Even with this defense, radiation can still cause sudden widespread errors affecting many qubits at once (error bursts). But it was not clear why.
Hourglass nanographenes unlock strong, robust multi-spin entanglement
Researchers from the National University of Singapore (NUS) and collaborators have developed a predictive design strategy for creating graphene-like molecules with multiple interacting spins and enhanced resilience to magnetic perturbations, opening new avenues for molecular-scale quantum information technologies and next-generation spintronics.
The research team was led by Professor Lu Jiong from the NUS Department of Chemistry and the NUS Institute for Functional Intelligent Materials, together with Professor Wu Jishan from the NUS Department of Chemistry, and international collaborators, including key contributor Professor Pavel Jelínek from the Czech Academy of Sciences in Prague.
Magnetic nanographenes, which are molecules composed of fused benzene rings, are of growing interest for quantum technologies because they can host unpaired electrons, or spins, that may be used to store and process information. Unlike conventional magnetic materials based on metal atoms, these carbon-based systems offer chemical versatility and long spin coherence times. However, engineering a single molecule that contains multiple strongly coupled spins in a stable and controlled manner remains a major challenge.
Durable ionogel withstands 5,000 times its weight while staying soft on skin
The development of soft materials that can reliably function on the human body is important for the future of bioelectronics and wearable medical devices. These materials need to comfortably conform to the skin while being durable enough for everyday use. However, many existing soft materials are easily damaged, limiting their practical applications.
A research team led by Professor Lizhi Xu from the Department of Mechanical Engineering under the Faculty of Engineering at the University of Hong Kong (HKU) has created a new type of ionogel that overcomes this challenge. The material is soft and flexible, yet strong enough to withstand significant mechanical stress, making it ideal for wearable and biomedical applications.
The research is published in the journal Science Advances, in an article titled “High-strength and fracture-resistant ionogels via solvent-tailored interphase cohesion in nanofibrous composite networks.”
Time-varying magnetic fields can engineer exotic quantum matter
Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While already in use primarily in laboratory and research settings globally, quantum technologies are in a transition phase for broader industry applications across many economic sectors.
In researching fundamental aspects of quantum physics, or the behavior of nature at the smallest scales—involving atoms, electrons and photons—a study led by Cal Poly Physics Department Lecturer Ian Powell analyzed how a changing magnetic field can make matter behave in unusual ways.
Powell and student researcher Louis Buchalter, who graduated with a Cal Poly bachelor’s degree in physics in 2025, published the article “Flux-Switching Floquet Engineering” in the journal Physical Review B, highlighting how changing magnetic fields over time can create quantum states that do not exist in any stationary material (remaining in the same state as time elapses).
Oxford team achieves advanced quantum squeezing with trapped ion
“The result is more than the creation of a new quantum state. It is a demonstration of a new method for engineering interactions that were previously out of reach,” said Dr. Oana Băzăvan, lead author from the Department of Physics, University of Oxford.
“The fourth-order quadsqueezing interaction was generated more than 100 times faster than expected using conventional approaches. This makes effects that were previously out of reach accessible in practice,” Băzăvan added.
Physicists have long used a trick called “squeezing” to sharpen the fuzzy measurements of the subatomic world. It is why gravitational-wave detectors, like LIGO, can hear black holes colliding across the universe. But for all its utility, ordinary squeezing is a relatively simple, second-order effect.
XXP instrument back online, marking a key milestone in high-energy upgrade to SLAC’s X-ray laser
XPP, the X-ray Pump Probe instrument at the Linac Coherent Light Source (LCLS), is back online and welcoming researchers after a complete rebuild. The overhaul has readied XPP for the significant increase in X-ray output expected from the ongoing high-energy upgrade to LCLS at the Department of Energy’s SLAC National Accelerator Laboratory. LCLS is a pioneering X-ray free-electron laser facility used by scientists around the world to capture ultrafast snapshots of natural processes.
“Completing the XPP rebuild on-time and on-budget is a key milestone for the high-energy upgrade effort, and we’re thrilled that the instrument is back to supporting researchers from around the world,” said John Hogan, project director for the LCLS high-energy upgrade. “This was a huge team effort, involving partners across SLAC’s engineering, science and project teams.”
Since its 2010 debut, XPP has enabled groundbreaking research across materials science—from quantum information storage to material dynamics across timescales—as well as studies in chemistry, physics and bioscience. Researchers have leveraged XPP to pioneer X-ray optics technologies, including cavity-based X-ray oscillators that are shaping future X-ray free-electron laser facilities.
Gene circuits reshape DNA folding and affect how genes are expressed, study finds
When a gene is turned on in a cell, it creates a ripple effect along the DNA strand, changing the physical structure of the strand. A new study by MIT researchers, appearing in Science, shows that these ripples can stimulate or suppress neighboring genes. These effects, which result from the winding or unwinding of neighboring DNA, are determined by the order of genes along a strand of DNA. Genes upstream of the active gene are usually turned up, while those downstream are inhibited.
The new findings offer guidance that could make it easier to control the output of synthetic gene circuits. By altering the relative ordering and arrangement of genes (gene syntax), researchers could create circuits that synergize to maximize their output, or that alternate the output of two different genes.
“This is really exciting because we can coordinate gene expression in ways that just weren’t possible before,” says Katie Galloway, an assistant professor of chemical engineering at MIT. “Syntax will be really useful for dynamic circuits. Now we have the ability to select not only the biochemistry of circuits, but also the physical design to support dynamics.”
Laser-plasma accelerators can preserve polarization of Helium-3 ions
Particle accelerators such as those at the European Organization for Nuclear Research (CERN) in Geneva are typically highly complex large-scale devices. In these ring-shaped facilities, which are often several kilometers in length, magnets and radio-frequency cavities are used to accelerate elementary particles. An alternative approach is now emerging: compact laser–plasma accelerators that can be built and operated at a fraction of the cost. These accelerators can achieve acceleration gradients up to around 1,000 times higher than those of conventional accelerators. Researchers at HHU contributed significantly to this development.
A research team led by Prof. Dr. Markus Büscher, a professor of physics at HHU and group leader at the Peter Grünberg Institute in Jülich, presented the current state of research in a review article in Reports on Progress in Physics. In a separate study published in High Power Laser Science and Engineering, they report on one specific aspect of laser–plasma acceleration, namely whether the polarization—that is to say, the collective spin alignment—of accelerated particles is preserved in laser–plasma accelerators.
Why is this relevant? “Spin alignment is crucial to a range of fundamental scientific questions as it influences the interaction between particles,” explains Professor Büscher. “In controlled nuclear fusion, the reaction probability—and thus ultimately the energy produced in the reactor—increases significantly when the spins of the fusing nuclei, the ‘fusion fuel’ so to speak, are aligned in parallel.”
