New ‘shape-shifting’ architecture brings versatility to photonic quantum computing

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.

Boron layers could set a superconductivity record, theoretical study predicts

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.

XENONnT detector narrows the hunt for dark matter

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. In the latest analysis from the XENON collaboration, working at the Gran Sasso National Laboratory in Italy, researchers carried out a “blind” test to avoid bias in measurements of the […]

Physicists watch a material’s electrons assemble, and reassemble, into coexisting phases

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.

An elegant modification doubles the range of low-noise ‘white lasers’ in a single fiber

Supercontinuum light sources—often called “white lasers” because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. 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.

New quantum microscopy trick quadruples microscope resolution

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 […]

Single-shot phase imaging technique can reconstruct transparent objects

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 […]

Never-before-seen woven structure that forms naturally inside a crystal discovered

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.

Researchers demonstrate first fully solution-processed solid-state polariton laser

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 […]

Two-qubit entangling gate flags its own errors as detectable photon losses

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.

X(2370) emerges as glueball-dominated particle in collider experiments

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⁻⁺.

Repurposing deep-Earth tools in the hunt for practical superconductors

If scientists could find a material that acts as a superconductor—that is, one that transmits energy with zero resistance—at normal pressures and relatively high temperatures, it would open up a vast number of possibilities. These include medical imaging, quantum computing and numerous other fields. So, yes, it would be a big deal.

Sunlight-powered setup generates quantum entanglement

Today’s quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that quantum entanglement between photons can be generated directly from sunlight, offering a potential alternative.

Miniaturized laser technology paves the way for fundamental physics experiments in space

An international team of researchers has succeeded in producing atomic quantum gas mixtures with an unprecedented particle flux. In the journal Nature Communications, the scientists report on experiments conducted with the MAIUS-B apparatus, in which Bose–Einstein condensates (BECs) consisting of two different atomic species—rubidium and potassium—were generated and studied under microgravity conditions in the Einstein […]

Air-stable, ultrathin superconductors developed for more scalable quantum devices

Super-thin superconducting materials, which are only one or a few atoms thick, have unique properties scientists can leverage to produce more compact, scalable, and efficient quantum devices. But these fragile materials degrade so rapidly in air that they are difficult to study or manufacture.
