Quantum computers have the potential to perform calculations more quickly than supercomputers, but they could be even faster and more energy-efficient if they were built with photons as their basic units, called qubits. https://phys.org/news/2026-11-advances-quantum-harnesses.html Quantum Physics Thu, 12 Nov 2026 22:40:01 EST news713708768 A recent study published in Nature Electronics and carried out by researchers from nanoGUNE's Quantum Hardware research group, Quantum Motion, London Center for Nanotechnology, Imperial College London and the University of Cambridge introduces a new superinductor created within a silicon integrated circuit fabricated in a commercial complementary metal–oxide–semiconductor (CMOS) process. https://phys.org/news/2026-11-superinductor-silicon-circuit.html Superconductivity Wed, 04 Nov 2026 17:40:08 EST news713015403 When you think about making computer chips better, you probably think about transistors. My colleagues and I focused on a less visible part of the problem: the components that deliver power to those transistors. A chip needs more than electricity. It needs electricity supplied at the right voltage, with fluctuations kept under control. Making the hardware that does this smaller is an important challenge—and one that led my colleagues and me to build tiny magnetic devices called stripline microinductors. https://phys.org/news/2026-11-magnetic-nanocomposites-components-power-chips.html Nanophysics Mon, 02 Nov 2026 17:20:02 EST news712840879 Researchers at Umea university thought gold particles would make electronic components emit more light.

Now, a team led by Darrell Schlom at Cornell University has shown that adding silicon to thin films of aluminum gallium oxide can keep this control intact at bandgaps wider than any semiconductor before it. Their research has been published in Nature. https://phys.org/news/2026-10-sapphire-grown-semiconductor-bandgap.html Condensed Matter Thu, 22 Oct 2026 07:00:04 EDT news711713518 Today's computer technology, based on silicon chips, is slowly reaching its physical limits. Components cannot be miniaturized indefinitely, and clock speeds cannot be increased indefinitely. At the same time, huge AI data centers are being built in many places, and these consume an immense amount of electricity. This is why scientists around the world are searching for novel materials that can replace or complement silicon technology and consume significantly less electricity. https://phys.org/news/2026-10-rays-reveal-copper-oxide.html Condensed Matter Mon, 19 Oct 2026 11:40:06 EDT news711621013 A transistor normally requires several fundamentally different materials—a semiconductor to carry current, an insulating dielectric to control it and metallic contacts through which current enters and leaves. Integrating all of these components becomes increasingly difficult as semiconductor devices approach the atomic scale. https://phys.org/news/2026-10-2d-crystal-transistor-built-insulation.html Nanophysics Thu, 15 Oct 2026 16:40:06 EDT news711293041 To build the ultrafast computers of the future, scientists are looking beyond the electrical charge of electrons to another property: their spin.
