Published Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon
(via sciencedaily.com) Tenacity has taken a roadblock and turned it into a possible route to the development of quantum computing.
Published Securing supply chains with quantum computing
(via sciencedaily.com) New research in quantum computing is moving science closer to being able to overcome supply-chain challenges and restore global security during future periods of unrest.
Published When the light is neither 'on' nor 'off' in the nanoworld
(via sciencedaily.com) Scientists detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
Published Researchers detail never-before-seen properties in a family of superconducting Kagome metals
(via sciencedaily.com) Researchers have used an innovative new strategy combining nuclear magnetic resonance imaging and a quantum modeling theory to describe the microscopic structure of Kagome superconductor RbV3Sb5 at 103 degrees Kelvin, which is equivalent to about 275 degrees below 0 degrees Fahrenheit.
Published Scientists boost quantum signals while reducing noise
(via sciencedaily.com) Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum systems by an order of magnitude. Their device is the first to demonstrate squeezing over a broad frequency bandwidth of 1.75 gigahertz, nearly two orders of magnitude higher than other architectures.
Published Endangered Bahamas bird may be lost from island following hurricane
(via sciencedaily.com) The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.
Published Severe weather straining electrical grids: New research mitigates demand surges, increasing grid reliability and reducing costs
(via sciencedaily.com) Concerns are mounting among policymakers and utility companies amid the impact of severe weather on the nation's electrical grids. In recent months, electrical grids in Texas have been tested to the point of near failure. So it seems like perfect timing that new research identifies a new method that provides the best way to utilize 'direct load control contracts' to mitigate electricity demand surges, increase grid reliability and reduce electricity cost. All of this right down to the individual household.
Published Scientists make major breakthrough in developing practical quantum computers that can solve big challenges of our time
(via sciencedaily.com) Researchers have demonstrated that quantum bits (qubits) can directly transfer between quantum computer microchips and demonstrated this with record-breaking connection speed and accuracy. This breakthrough resolves a major challenge in building quantum computers large and powerful enough to tackle complex problems that are of critical importance to society.
Published New research suggests drought accelerated empire collapse
(via sciencedaily.com) Original source The collapse of the Hittite Empire in the Late Bronze Age has been blamed on various factors, from war with other territories to internal strife. Now, scientists have used tree ring and isotope records to pinpoint a more likely culprit: three straight years of severe drought.
Published Devastating cost of future coastal flooding for many developing nations predicted in new study
(via sciencedaily.com) New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.
Published More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice
(via sciencedaily.com) The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say
(via sciencedaily.com) Original source Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published Entangled atoms cross quantum network from one lab to another
(via sciencedaily.com) Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.
Published Researchers devise a new path toward 'quantum light'
(via sciencedaily.com) Researchers have theorized a new mechanism to generate high-energy 'quantum light', which could be used to investigate new properties of matter at the atomic scale.
Published Mapping Mexico's dengue fever hotspots
(via sciencedaily.com) Scientists have analyzed data from Mexico's Ministry of Health to identify dengue fever hotspots. Working with epidemiologists at the University of North Texas and Universidad Autónoma de Nuevo León, the team calculated environmental and socioeconomic risk factors and mapped areas where severe outbreaks occur.
Published Wildfires are increasingly burning California's snowy landscapes and colliding with winter droughts to shrink California's snowpack
(via sciencedaily.com) A research team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe wildfire.
Published Far-off storms fuel sneaker waves along Pacific Northwest coast, new research suggests
(via sciencedaily.com) Sneaker waves are likely fueled by a specific type of wave condition generated by far-off storms and paired with just the right conditions closer to shore, a new study has found.
Published Researchers take a step toward novel quantum simulators
(via sciencedaily.com) If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Published Understanding plants can boost wildland-fire modeling in uncertain future
(via sciencedaily.com) A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.
Published Monitoring an 'anti-greenhouse' gas: Dimethyl sulfide in Arctic air
(via sciencedaily.com) Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate.
