Overcoming one of the challenges of quantum mechanics: A major result in quantum mechanics has been achieved: for the first time, the temporal evolution of a quantum system has been manipulated through interaction with light oulses in the extreme ultraviolet (XUV). This achievement has been obtained by a team of researchers coordinated by Prof. Lukas Bruder from the University of Freiburg, in collaboration with 14 international institutes, including the Politecnico di Milano, the Institute of Photonics and Nanotechnologies of the…

New radio astronomy observations of a planetary system in the process of forming show that once the first planets form close to the central star, these planets can help shepherd the material to form new planets farther out. In this way each planet helps to form the next, like a line of falling dominos each triggering the next in turn. To date over 5000 planetary systems have been identified. More than 1000 of those systems have been confirmed to host…

Also known as Virgo A or NGC 4486, M87 is the brightest object in the Virgo cluster of galaxies, the largest gravitationally bound type of structure in the universe.

The development marks a major step forward in laser-plasma acceleration, a promising method for making compact, high-energy particle accelerators that could have applications in particle…

New research demonstrates a brand-new architecture for scaling up superconducting quantum devices. Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have  realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution demands. Unlike the typical quantum chip design that lays the information-processing qubits onto a 2-D grid, the team from the Cleland Lab has designed a modular quantum processor comprising a reconfigurable router as a…

Current laser technologies for the extended SWIR spectral range rely on expensive and complex materials, limiting their scalability and affordability.

International research team presents first electrically pumped continuous-wave semiconductor laser suitable for seamless silicon integration. Scientists from Forschungszentrum Jülich, FZJ, the University of Stuttgart, and the Leibniz Institute for High Performance Microelectronics (IHP), together with their French partner CEA-Leti, have developed the first electrically pumped continuous-wave semiconductor laser composed exclusively of elements from the fourth group of the periodic table – the “silicon group”. Built from stacked ultrathin layers of silicon germanium-tin and germanium-tin, this new laser is the first…

A new study by Rice University physicist Qimiao Si unravels the enigmatic behaviors of quantum critical metals — materials that defy conventional physics at low temperatures. Published in Nature Physics Dec. 9 , the research examines quantum critical points (QCPs), where materials teeter on the edge between two distinct phases such as magnetism and nonmagnetism. The findings illuminate the peculiarities of these metals and provide a deeper understanding of high-temperature superconductors, which conduct electricity without resistance at relatively high temperatures….

Encountering Neptune in 1989, NASA’s Voyager mission completed humankind’s first close-up exploration of the four giant outer planets of our solar system. Collectively, since their launch in 1977, the twin Voyager 1 and Voyager 2 spacecraft discovered that Jupiter, Saturn, Uranus, and Neptune were far more complex than scientists had imagined. There was a lot more to be learned. A NASA Hubble Space Telescope observation program called OPAL (Outer Planet Atmospheres Legacy) obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand…

DFKI develops autonomous underwater robot to monitor marine biodiversity. Sustainable monitoring of the marine environment is crucial for the environmentally responsible operation of offshore wind farms and the protection of biodiversity. In the SeaMe project, RWE is collaborating with leading research partners to develop innovative technologies for comprehensive ecosystem monitoring.

The German Research Center for Artificial Intelligence (DFKI) is contributing by equipping an autonomous underwater vehicle with oceanographic sensors and…

“Our results have no clear or direct application right now. It’s basic research that lays the foundation for future technologies in quantum information and quantum computers. There’s enormous potential for completely new discoveries in many different research fields,” says Guilherme B Xavier, researcher in quantum communication at Linköping University, Sweden. But to understand what the researchers have shown, we need to start at the beginning. That light can be both particles and waves is one of the most illogical –…

Researchers from Singapore and China have used a superconducting quantum processor to study the phenomenon of quantum transport in unprecedented detail.
