Twisting and binding matter waves with photons in a cavity
Precisely measuring the energy states of individual atoms has been a historical challenge for physicists due to atomic recoil. When an atom interacts with a photon, the atom "recoils" in the opposite direction, making it difficult to measure the posi.....»»
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.....»»
Qualcomm says lower-end Snapdragon X Plus chips can still outrun Apple’s M3
Same NPU, same architecture as X Elite, but fewer cores and lower clock speeds. Enlarge (credit: Qualcomm) Qualcomm’s Snapdragon X series of chips promises to be the company’s first that can go toe-to-toe with Apple.....»»
Scientists tune the entanglement structure in an array of qubits
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior.....»»
iPadOS 18 could ship with built-in Calculator app, after 14 Calculator-less years
Every single iPhone and Mac has come with a calculator app, but not the iPad. Enlarge (credit: Apple/Andrew Cunningham) Last year, Apple introduced the ability to set multiple timers at once in the Clock app on its vario.....»»
Manipulating the geometry of the "electron universe" in magnets
Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum states in a manner math.....»»
Magnetic with a pinch of hydrogen: Research team develops new idea to improve the properties of ultra-thin materials
Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the.....»»
Estimating uncertainty in atomic spectroscopy
If you repeat a measurement with the same or different instruments, you'll get slightly different numbers each time. Estimating the uncertainties associated with these numbers turns them into an informative result......»»
Vibrations of granular materials: Theoretical physicists shed light on an everyday scientific mystery
Coffee beans in a jar and piles of rice or sand are examples of granular matter: materials composed of large numbers of macroscopic—rather than atomic scale—particles. Although granular matter is extremely familiar in everyday life, it represents.....»»
Study finds iron-rich enamel protects, but doesn"t color, rodents" orange-brown incisors
Chattering squirrels, charming coypus, and tail-slapping beavers—along with some other rodents—have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the.....»»
The best processor for video editing in 2024 across all budgets
These are the best CPUs for video editing, each with high clock speeds, lots of cores, and all the power you need......»»

New technique lets scientists create resistance-free electron channels
An international research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state—an exotic quantum phenomenon that could help res.....»»
Computing how quantum states overlap
Quantum many-body systems are things such as atomic nuclei that consist of many tiny particles moving in complex ways. This makes it extremely difficult to predict how the systems behave as the particles interact. To study these systems, researchers.....»»
GM’s Cruise poised to resume testing robotaxis in Phoenix
A Cruise spokesman said the company “had not set a timeline for deployment. We are in the process of meeting with officials in select markets to gather information, share updates and rebuild trust.”.....»»
Team presents new path to long-term data storage based on atomic-scale defects
With the development of the internet, social media and cloud computing, the amount of data created worldwide on a daily basis is sky-rocketing. This calls for new technologies that could provide higher storage densities combined with secure long-term.....»»
