Scientists gain insight into the material defects that cause errors in quantum computing

Posted by in categories: computing, quantum physics

A team of researchers, led by scientist Lin Zhou of Ames National Laboratory, has made important progress towards understanding the role of surface oxides in improving quantum computing circuits performance. Surface oxides are a primary cause of decoherence, or loss of quantum properties in quantum circuits.

New deep ultraviolet micro-LED array advances maskless photolithography

Posted by in category: computing

A team led by Prof. Sun Haiding from the University of Science and Technology of China (USTC) developed a vertically integrated micro-scale light-emitting diode (micro-LED) array which was then applied in deep ultraviolet (DUV) maskless photolithography system for the first time. Their study was published in Laser & Photonics Reviews.

For heating plasma in fusion devices, researchers unravel how electrons respond to neutral beam injection

Posted by in categories: nuclear energy, particle physics

Heating a plasma for fusion research requires megawatts of power. One approach that research tokamaks use to achieve the necessary power input is neutral beam injection (NBI). With NBI, fast neutral particles are generated in a device called a beam source and then injected into the plasma.

Successful experiment paves the way for discovery of a new element

Posted by in categories: chemistry, physics

The search for new elements comes from the dream of finding a variant that is sufficiently stable to be long-lived and not prone to immediate decay. There is a theory in nuclear physics about an island of stability of superheavy elements. This is a potential zone in the upper part of the periodic table of as-yet-undiscovered elements that could remain stable for longer than just a few seconds. The aim is to explore the limits of stability of atomic nuclei.

Superconductivity researchers solve the mystery of Fermi arcs

Posted by in categories: materials, physics

High-temperature superconductivity is one of the great mysteries of modern physics: Some materials conduct electrical current without any resistance—but only at very low temperatures. Finding a material that remains superconducting even at room temperature would spark a technological revolution. People all over the world are therefore working on a better, more comprehensive understanding of such materials.

Researchers use high-performance computing to analyze a quantum photonics experiment

Posted by in categories: computing, quantum physics

For the first time ever, scientists at Paderborn University have used high-performance computing (HPC) at large scales to analyze a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a quantum detector. This is a device that measures individual photons.

Ghost Particles on Patrol: Antimatter Detector Revolutionizes Nuclear Reactor Monitoring

Posted by in categories: military, nuclear energy, particle physics

Researchers have developed a new detector that analyzes antineutrinos emitted by nuclear reactors to monitor their activities from great distances.

This technology, which utilizes the phenomena of Cherenkov radiation, could revolutionize how we ensure reactors are not producing material for nuclear weapons, despite challenges from other environmental antineutrinos.
