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.....»»
Scientists show that there is indeed an "entropy" of quantum entanglement
Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lami from the University of Amsterdam have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of entropy for the phenomenon of quan.....»»
China Has a Controversial Plan for Brain-Computer Interfaces
China's brain-computer interface technology is catching up to the US. But it envisions a very different use case: cognitive enhancement......»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
Here’s everything to consider when buying a CPU in 2024
Your CPU is at the center of your computer, handling the underlying math that makes your machine tick. In this guide, we show you how to choose a CPU......»»
No new Vision Pro before late 2026, and declining demand – neither matters
Mark Gurman’s latest Power On newsletter suggests that Apple isn’t expected to launch a new Vision Pro (or Vision something) model until the end of 2026. That follows another report last week, suggesting that demand for the spatial computer is.....»»
Researchers discover "topological Kerr effect" in two-dimensional quantum magnets
In a recent collaboration between the High Magnetic Field Center of the Hefei Institutes of Physical Science of Chinese Academy of Sciences, and the University of Science and Technology of China, researchers introduced the concept of the topological.....»»

The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the.....»»
Unveiling a new quantum frontier: Frequency-domain entanglement
Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has the unique ability to alter t.....»»
Demonstration of heralded three-photon entanglement on a photonic chip
Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of.....»»
Virtual reality can motivate people to donate to refugee crises regardless of politics
Political conservatives who watched a documentary on Syrian refugees with a virtual reality headset had far more sympathy for the people depicted in the film than those who viewed the same film on a two-dimensional computer screen......»»
Computer game helps students get better at detecting fake news
A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news. This is shown by a study conducted by researchers at Uppsala University and elsewhere......»»
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.....»»
AI designs active pharmaceutical ingredients quickly and easily based on protein structures
A new computer process developed by chemists at ETH Zurich makes it possible to generate active pharmaceutical ingredients quickly and easily based on a protein's three-dimensional surface. The new process, detailed in Nature Communications, could re.....»»
Research combines DNA origami and photolithography to move one step closer to molecular computers
Molecular computer components could represent a new IT revolution and help us create cheaper, faster, smaller, and more powerful computers. Yet researchers struggle to find ways to assemble them more reliably and efficiently......»»
Recoding Voyager 1—NASA’s interstellar explorer is finally making sense again
"We're pretty much seeing everything we had hoped for, and that's always good news.” Engineers have partially restored a 1970s-era computer on NASA's Voyager 1 spacecraft after five months of long-distance troubleshooting, building.....»»
