Scientists make and test efficient water-splitting catalyst predicted by theory
Hydrogen (H2) is a promising fuel for reducing greenhouse gases, especially if produced by using renewable energy to split water molecules (H2O). But as simple as it may seem to break water into hydrogen and oxygen, the chemistry is complex......»»
Pseudomagic quantum states: A path to quantum supremacy
A new study in Physical Review Letters (PRL) introduces the concept of pseudomagic quantum states, which appear to have high stabilizerness (or complexity) and can move us closer to achieving quantum supremacy......»»
"Quantum optical antennas" provide more powerful measurements on the atomic level
Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can use to study the fundamental.....»»
Novel quantum sensor breaks limits of optical measurement using entanglement
The Korea Research Institute of Standards and Science (KRISS) has developed a novel quantum sensor technology that allows the measurement of perturbations in the infrared region with visible light by leveraging the phenomenon of quantum entanglement......»»
How Game Theory Can Make AI More Reliable
Researchers are drawing on ideas from game theory to improve large language models and make them more correct, efficient, and consistent......»»
Nonreciprocal quantum batteries exhibit remarkable capacities and efficiency
In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which essentially means that a s.....»»
Quantum chemistry and simulation help characterize coordination complex of elusive element 61
When element 61, also known as promethium, was first isolated by scientists at the Department of Energy's Oak Ridge National Laboratory in 1945, it completed the series of chemical elements known as lanthanides. However, aspects of the element's exac.....»»
QUIET: A place to study qubits shielded from the effects of cosmic rays
Deep under the ground at Fermi National Accelerator Laboratory is a brand-new quantum sensor and computing research center called QUIET, and at the surface—100 meters above—sits its twin called LOUD......»»
Mapping noise to improve quantum measurements
One of the biggest challenges in quantum technology and quantum sensing is "noise"–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information......»»
Cutting-edge mathematics provides new tool for particle collision puzzle
Scientists have used computational algebraic geometry to study predictions for particle physics experiments, such as those at the Large Hadron Collider (LHC), which first detected the Higgs particle in 2012......»»
Unveiling novel energy phenomena from light exposure on layered materials
Research groups from the University of Tsukuba and the University of Rennes have discovered a novel phenomenon in which a nested structure of carbon nanotubes enveloped in boron nitride nanotubes facilitates a unique electron escape route when expose.....»»
Study of photons in quantum computing reveals that when photons collide, they create vortices
Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub......»»
Study suggests marine cyanobacteria communicate via membrane nanotubes
Three years ago, María del Carmen Muñoz, a researcher at the University of Cordoba, was peering into an electron microscope to study the vesicles of marine cyanobacteria and found, almost accidentally, something she did not expect: structures that,.....»»
Study links nanoparticles to altered blood vessel formation in embryos
Human life begins with a single egg cell that grows into a human being with trillions of cells. To ensure that the highly complex development of tissues and organs is as protected as possible, the placental barrier keeps pathogens and foreign substan.....»»
