- Chalmers Researchers Make Bosonic Quantum Operations More Than 1,000 Times Faster 17/09/2026 Researchers at Chalmers University of Technology developed a method that can perform a range of operations on bosonic quantum states in a single driving cycle, making some operations more than 1,000 times faster than previous approaches. The method uses quantum lattice gates and Floquet control to reduce the number of driving cycles needed to manipulate bosonic quantum codes in superconducting quantum circuits. The researchers say the approach could reduce exposure to errors during quantum operations and support future development of fault-tolerant quantum computing, with experimental demonstrations being discussed at Chalmers.
- Spinons may help electrons pair along stripes in some superconductors 15/09/2026 Superconductors are materials that carry electricity with zero resistance below specific temperatures. Many of these materials become superconducting at very low temperatures, yet some enter superconducting phases at higher temperatures.
- Magic-angle graphene provides evidence for unconventional superconductivity 11/09/2026 Researchers have completely suppressed superconductivity in magic-angle graphene by screening interactions between electrons, helping resolve a long-running debate about the origin of the phenomenon.
- Three quantum phases in chromium-based material hint at a spin-triplet superconductor 09/09/2026 Superconductors are materials that conduct electricity without electrical resistance when cooled below a specific critical temperature. These materials have proved promising for the development of various technologies, including medical imaging instruments, particle accelerators, ultrasensitive detectors and quantum processors.
- Unusual superconductivity could emerge in valley-imbalanced rhombohedral graphene 27/08/2026 Superconductors are materials in which electrical current flows with a resistance of zero, typically below specific temperatures. In conventional superconductors, this state of matter emerges when two electrons bind together at low temperatures, forming so-called Cooper pairs.
- A strange quantum effect dramatically boosts energy transfer 25/08/2026 Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started. This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalytic reactions.
- World’s first superconducting quantum heat engine could help unlock massive quantum computers 21/08/2026 A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum computers, potentially eliminating huge numbers of costly, noise-producing microwave cables.
- Controlling the rotation direction of light without complex new materials 20/08/2026 A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light that travels while rotating like a pinwheel to the left or right. Because different rotation directions can carry different information, it is drawing attention as a key light source for next-generation displays, optical communications and security technologies.

- New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells 11/08/2026 The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Electrochimica Acta, demonstrates a breakthrough made possible by applying controlled mechanical compression to the catalyst. This modifies its atomic-scale structure, enabling it to achieve energy efficiency comparable to that of pure platinum.
- Seven exotic quantum phases predicted in ultracold magnetic atoms, including topological superconductivity 14/07/2026 Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their properties difficult to understand even today. A research team from Innsbruck and Turin has now proposed a new theoretical framework for generating and studying these exotic states of matter in ultracold magnetic atoms in a one-dimensional lattice.
