Generating graph states of atomic ensembles via photon-mediated entanglement
Graph states, a class of entangled quantum states that can be represented by graphs, have been the topic of numerous recent physics studies, due to their intriguing properties. These unique properties could make them particularly promising for quantu.....»»
Mercedes’ patented steering may finally make EVs exciting to drive
It describes a way of generating feedback for the driver through the steering. New cars really are better than they used to be. They last longer, they're more efficient, and they'.....»»
Researchers synthesize carbon nanotubes with precise chirality
Researchers have achieved a significant breakthrough in the synthesis of carbon nanotubes (CNTs) by developing a novel catalyst that allows for precise control over their atomic arrangement, known as chirality. This advancement paves the way for the.....»»
"Making insurance effective in the face of climate change may require it to be legally enforced"
Recent hurricanes hitting the Southeastern United States have again robbed people of their homes, businesses and lives. Hurricane Helen, in late September, was followed up last week by Hurricane Milton, collapsing seemingly robust building structures.....»»
Integrated space-ground technologies empower archaeological research into ancient tombs
A team of international researchers has employed an integrated approach to uncover the mysteries of the Eastern Mausoleum of Qin State, an ancient royal burial site from China's Warring States period......»»
Fungi finding: mushroom hunters seek new species and recognition
You can't walk very far through a forest in this part of the United States without stumbling upon a mushroom, an eruption from a vast fungal kingdom that all life depends on, but about which we know very little......»»
Scientists create new overwintering sites for monarch butterflies on a warming planet
The migration of the monarch butterfly is one of the wonders of the natural world. Each autumn, a new generation of monarch butterflies is born in the northern United States and southern Canada. Hundreds of millions of these butterflies then fly to t.....»»
Democrats and Republicans agree on one thing: Censoring hate speech
There is strong disagreement in the United States as to whether, when and how much hate speech should be censored when posted on social media platforms. Democrats and Republicans, in particular, often argue about this question, especially in light of.....»»
Democracy in danger? Election study in East German states shows mistrust in the state
Survey results from Trier and Jena University show that in Saxony, Thuringia and Brandenburg democracy is in crisis. Most respondents do not want the AfD to participate in government......»»
New technique enhances precision in measuring short-lived atomic nuclei
Researchers at the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) have introduced a technique, Tune-IMS, designed to improve the precision of isochronous mass spectrometry (IMS) in measuring short-lived atomic nuclei. The development offers refin.....»»
Longer wildfire seasons means more bad air days
Each year in Utah and most other western states in America, the period from July through October is considered wildfire season because it typically represents the peak times atmospherically for such hazardous phenomenon. Besides the danger to propert.....»»
New method to generate photon pairs efficiently on a chip
Thin-film lithium niobate is an emerging nonlinear integrated photonics platform ideally suited for quantum applications. Through spontaneous parametric down-conversion (SPDC), it can generate correlated photon pairs for quantum key distribution, tel.....»»
Leap Seconds May Be Abandoned by the World’s Timekeepers
We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?.....»»
The neutron lifetime problem—and its possible solution
Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after about 15 minutes.....»»
Ship-mounted camera systems help increase protections for marine mammals
Vessel strikes and entanglement are some of the leading causes of injury and death to marine animals such as whales. Increasingly urbanized waterways, warming oceans, changes in prey distribution—and in some cases, increasing species populations—.....»»
Two million voters with felony convictions have the right to vote—but might not know
As get-out-the-vote efforts hit high gear nationwide, a team of sociologists, political scientists and nonprofits in select states are focused on reaching out to some of the more than two million people with felony convictions who may not realize the.....»»
A historical perspective on megafires and roadway damage in Washington, Oregon and California
A research team has examined the extent of damage and associated costs on the 2020 Labor Day wildfires in Washington, Oregon, and California, comparing results with the historical impact of megafires in these states......»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
Dual-species atomic arrays show promise for quantum error correction
A study in Nature Physics has realized a dual-species Rydberg array combining rubidium (Rb) and cesium (Cs) atoms to enhance quantum computing and its applications......»»
How nation-states exploit political instability to launch cyber operations
In this Help Net Security interview, Ismael Valenzuela, Vice President of Threat Research & Intelligence at BlackBerry, discusses the impact of geopolitical tensions on the frequency and sophistication of cyberattacks. He explains how nation-states a.....»»
Digital quantum simulation of nuclear magnetic resonance experiments
Programmable quantum computers have the potential to efficiently simulate increasingly complex molecular structures, electronic structures, chemical reactions, and quantum mechanical states in chemistry that classical computers cannot. As the molecul.....»»
