Scientists realize bulk high-temperature superconductivity in material under high pressure

9 octobre

Recent findings of signatures of high-temperature superconductivity (HTSC) with Tc ≈ 80K at pressures above 14GPa in the crystals of La3Ni2O7 have attracted tremendous research interest as a new family of HTSC.

New photonics approach enhances quantum computation efficiency

9 octobre

A recent study, published in Nature Photonics, by Prof. Yaron Bromberg and Dr. Ohad Lib from the Racah Institute of Physics at the Hebrew University of Jerusalem has made significant strides in advancing quantum computing through their research on photonic-measurement-based quantum computation.

Merging atomic clocks with quantum computers could lead to ultraprecise measurements of laws of nature

9 octobre

Physicists like to measure things, and they like those measurements to be as precise as possible. That means working at unfathomably small scales, where distances are much smaller than even the diameters of subatomic particles. Researchers also want to measure time down to a precision of less (…)

New AI models of plasma heating lead to important corrections in computer code used for fusion research

9 octobre

New artificial intelligence (AI) models for plasma heating can do more than was previously thought possible, not only increasing the prediction speed 10 million times while preserving accuracy, but also correctly predicting plasma heating in cases where the original numerical code failed. The (…)

Novel technique for observing atomic-level changes could unlock potential of quantum materials

9 octobre

A research team led by the Department of Energy’s Oak Ridge National Laboratory has devised a unique method to observe changes in materials at the atomic level. The technique opens new avenues for understanding and developing advanced materials for quantum computing and electronics. The paper is (…)

Smart new laser technology can monitor greenhouse gases faster, more sensitively

9 octobre

Scientists at the National Institute of Standards and Technology (NIST) have developed a new laser-based technique that could dramatically improve our ability to analyze a variety of materials and gases, including greenhouse gases. This new method, called "free-form dual-comb (…)

Major upgrade of the High-Luminosity LHC to be tested in an above-ground facility

9 octobre

An impressive operation recently took place in CERN’s magnet test hall. The innovative cold powering system has been successfully installed in the High-Luminosity LHC (HL-LHC) Inner Triplet (IT) String test stand.

Accelerator studies propel quantum research into a higher energy orbit

9 octobre

Physicists share a common interest in understanding how the physical world works. For example, when a particle physicist breaks apart a particle into smaller pieces, they ask themselves : are those the smallest pieces we can find in nature ?

Nobel Prize in physics spotlights key breakthroughs in AI revolution—making machines that learn

9 octobre

If your jaw dropped as you watched the latest AI-generated video, your bank balance was saved from criminals by a fraud detection system, or your day was made a little easier because you were able to dictate a text message on the run, you have many scientists, mathematicians and engineers to thank.

Quantum physicists tap into entanglement to improve the precision of optical atomic clocks

9 octobre

Imagine walking into a room where several different grandfather clocks hang on the walls, each ticking at a different pace. Quantum physicists at the University of Colorado Boulder and the National Institute of Standards and Technology (NIST) have essentially recreated that room at the scale of (…)
