Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, this has not yet been demonstrated. Research therefore relies heavily on theoretical models and simulations to explore where and under what conditions such an advantage may realistically be achieved in the future. https://phys.org/news/2026-08-quantum-advantage-reassessed-realistic-benchmarks.html General Physics Wed, 12 Aug 2026 09:20:08 EDT news705742802 Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity at higher temperatures. https://phys.org/news/2026-08-sought-zhang-rice-singlet-visualized.html Superconductivity Wed, 12 Aug 2026 08:00:01 EDT news705663782 A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished. https://phys.org/news/2026-08-cern-conventional-gluons-atomic-nuclei.html General Physics Tue, 11 Aug 2026 17:40:04 EDT news705672722 New research introduces a contactless way to see how mirror-image materials respond differently to circularly polarized light, without first building them into a complete electronic device. The researchers developed a novel method based on light-induced charge separation that allows researchers to directly probe how the material's structure acts like a microscopic filter, influencing how electrons separate and move. https://phys.org/news/2026-08-contactless-method-reveals-mirror-image.html Condensed Matter Tue, 11 Aug 2026 16:20:04 EDT news705670261 When certain atoms are irradiated with laser light, they can produce a very different kind of laser light: laser pulses with extremely high frequencies in the X-ray range. These laser pulses, which helped achieve record-breaking results at TU Wien in the 1990s, were the subject of the 2023 Nobel Prize in Physics. https://phys.org/news/2026-08-rays-nobel-prize-limit.html Optics & Photonics Tue, 11 Aug 2026 13:40:07 EDT news705665527 Researchers at the University of Basel and the Technical University of Munich have developed a new method to reveal the collective motion of electrons in one of the most elusive states of matter: the Wigner crystal. Using light, the physicists were able to uncover previously inaccessible properties of this fragile quantum state. https://phys.org/news/2026-08-optical-method-reveals-internal-dynamics.html Optics & Photonics Tue, 11 Aug 2026 05:00:03 EDT news705591481 Every electronic and optoelectronic device generates heat, and today that heat is managed almost entirely from the outside. Heatsinks, fans, cold plates and refrigerators are bulky exterior measures bolted onto a chip or package after the fact. They treat heat as a single averaged quantity to be removed in bulk, even though the heat is actually produced locally, component by component, deep inside the circuitry. https://phys.org/news/2026-08-quantum-circuits-electronics-oldest-power.html Condensed Matter Mon, 10 Aug 2026 16:40:10 EDT news705585471 In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours. In a new study published in Nature Communications, Professor Alex Greilich and his team show that many such time crystals can form in the same material and synchronize their electron-nuclear spin oscillations. https://phys.org/news/2026-08-distant-crystals-oscillate-unison-paving.html Condensed Matter Mon, 10 Aug 2026 16:20:09 EDT news705593161 Over the last decade, researchers have developed two-dimensional materials with fascinating quantum effects that could be harnessed for next-generation technologies. https://phys.org/news/2026-08-discovery-electrons-2d-material-memory.html Condensed Matter Mon, 10 Aug 2026 13:20:05 EDT news705584761 Skyrmions—essentially magnetic vortices—represent a promising approach in spintronics; in the future, they could serve as components in storage media or computers, potentially complementing established CMOS technologies. Researchers at Johannes Gutenberg University Mainz (JGU) have now visualized the interaction of antiferromagnetic skyrmions for the first time and shown that antiferromagnetic skyrmions move reproducibly along straight trajectories aligned with the driving electric current. https://phys.org/news/2026-08-real-reveal-antiferromagnetic-skyrmions-line.html Condensed Matter Mon, 10 Aug 2026 12:00:03 EDT news705581582 Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying mirror" that hides information carried by an input image and transforms it into a misleading, ordinary-looking pattern at the output. The study is published in the journal Nature Communications. https://phys.org/news/2026-08-mirror-surfaces-conceal-optical.html Optics & Photonics Mon, 10 Aug 2026 09:40:02 EDT news705572941 From schools of fish and flocks of birds to microscopic synthetic particles, many systems in nature and the laboratory consist of individual units or agents that move by consuming energy. These systems are known as active matter because their components continuously use energy to generate motion, either individually or through interactions with their environment. https://phys.org/news/2026-08-tiny-particles-defy-action-reaction.html General Physics Sun, 09 Aug 2026 12:40:01 EDT news705316928 In a new Nature Physics study, researchers accelerated electrons to more than twice the energy predicted by the traditional dephasing limit for laser-plasma accelerators operating over the same distance. This was made possible by a specially engineered laser pulse called a flying focus, which counteracts a longstanding limitation known as "dephasing." https://phys.org/news/2026-08-flying-focus-laser-key-limitation.html Optics & Photonics Sat, 08 Aug 2026 15:40:03 EDT news705318688 For the first time, researchers have determined the shape of the actinide nucleus of fermium-255 and measured its structure with high precision and resolution. https://phys.org/news/2026-08-laser-spectroscopy-reveal-hidden-nuclear.html General Physics Fri, 07 Aug 2026 17:20:01 EDT news705325561 Using light to process quantum information is one of the most promising approaches to building future quantum computers. Light particles, known as photons, are excellent carriers of quantum information, but their lack of natural interactions has created a major challenge for researchers seeking to build systems capable of performing a full range of computations. https://phys.org/news/2026-08-shifting-architecture-versatility-photonic-quantum.html Optics & Photonics Fri, 07 Aug 2026 17:00:01 EDT news705325201 In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"—my son, it is only a wisp of fog. In the poem, the father's reassurance proves tragically wrong. In the quantum world, however, his words acquire an uncanny new meaning. https://phys.org/news/2026-08-mirror-world-particles-wisps-fog.html General Physics Fri, 07 Aug 2026 16:40:02 EDT news705324723 Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires expensive or bulky equipment, such as liquid-helium cooling tanks or specially shielded rooms that block out Earth's magnetic field. https://phys.org/news/2026-08-tiny-magnet-ultrafaint-magnetic-fields.html General Physics Fri, 07 Aug 2026 16:20:02 EDT news705322283 Scientists in China predict that stacking two microscopic layers of boron could set a new record for superconductivity. Superconductors are materials that conduct electricity with zero resistance. Traditional types need temperatures close to absolute zero to work, requiring complex and expensive cooling equipment. https://phys.org/news/2026-08-boron-layers-superconductivity-theoretical.html Condensed Matter Fri, 07 Aug 2026 15:20:01 EDT news705241771 A tall glass of ice water isn't just a thirst quencher; it's also an everyday example of coexisting phases. Water can exist simultaneously in both liquid and solid phases. As it turns out, this phase duality can also exist in more exotic quantum materials, in ways that are far more complicated to tease apart. https://phys.org/news/2026-08-physicists-material-electrons-reassemble-coexisting.html Condensed Matter Fri, 07 Aug 2026 12:00:01 EDT news705315901 Using a detector filled with nearly 9 metric tons of liquid xenon, researchers have delivered some of the most sensitive dark matter results ever recorded.

However, researchers have historically faced a frustrating trade-off: A broad spectrum comes at the expense of high fluctuations, which has effectively limited their use. https://phys.org/news/2026-08-elegant-modification-range-noise-white.html Optics & Photonics Thu, 06 Aug 2026 19:00:03 EDT news705252541 Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons. This makes the platform not only a new type of solution-processed laser but also a powerful way to study nonlinear polariton interactions. The paper is published in the journal Nature Communications. https://phys.org/news/2026-08-fully-solution-solid-state-polariton.html Condensed Matter Thu, 06 Aug 2026 18:00:06 EDT news705251523 For the first time, scientists have observed a three-dimensional woven structure forming naturally inside a crystal, revealing a previously unknown way in which matter can organize itself. https://phys.org/news/2026-08-woven-naturally-crystal.html Condensed Matter Thu, 06 Aug 2026 17:50:01 EDT news705255901 A KAIST research team led by professor Mooseok Jang from the Department of Bio and Brain Engineering has developed a single-shot phase imaging technique that reconstructs a phase object—a transparent object such as glass, plastic film or a living cell, which produces almost no visible contrast under an ordinary camera but induces a subtle shift in light called a phase change—from a single measurement, even when the object is fully enclosed between two dynamic scattering layers. https://phys.org/news/2026-08-shot-phase-imaging-technique-reconstruct.html Optics & Photonics Thu, 06 Aug 2026 17:20:03 EDT news705251821 Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now achieved a fourfold resolution boost compared to a classical microscope, using a new optical design that sends one of the entangled photons through the microscope's optics three times rather than just once. https://phys.org/news/2026-08-quantum-microscopy-quadruples-microscope-resolution.html Optics & Photonics Thu, 06 Aug 2026 17:20:01 EDT news705248785 At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball with spin-parity quantum numbers of 0⁻⁺. https://phys.org/news/2026-08-x2370-emerges-glueball-dominated-particle.html General Physics Thu, 06 Aug 2026 13:00:01 EDT news705231062 Quantum errors are a normal part of quantum computing because fragile physical qubits (the tiny components storing data) can easily break down because of environmental noise, like heat, stray signals or microscopic vibrations. Typical fixes involve vast amounts of extra hardware qubits, which make computers larger, more expensive and harder to build. https://phys.org/news/2026-08-qubit-entangling-gate-flags-errors.html Optics & Photonics Thu, 06 Aug 2026 12:40:01 EDT news705228588 Today's quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands.
