Imaging the elusive skyrmion: Neutron tomography reveals their shapes and dynamics in bulk materials

Posted by in categories: climatology, computing, information science

Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm to reveal for the first time the 3D shapes and dynamics of very small tornado-like atomic magnetic arrangements in bulk materials.

These collective atomic arrangements, called skyrmions—if fully characterized and understood—could be used to process and store information in a densely packed form that uses several orders of magnitude less energy than is typical now.

The conventional, semiconductor-based method of processing information in binary form (on or off, 0 or 1) employs electrical charge states that must be constantly refreshed by current which encounters resistance as it passes through transistors and connectors. That’s the main reason that computers get hot.

What is quantum squeezing?

Posted by in categories: internet, quantum physics

How many times have you shown up to a video meeting with people at work only to find you have terrible internet that day? Maybe the others on the call are cutting in and out, or maybe your own signal is being corrupted on their screen. Regardless, many remote workers have found a simple solution—turn down the video quality and focus on audio.

In a very general sense, this is the same technique that researchers leverage when using quantum squeezing to improve the performance of their sensors. Mark Kasevich, a professor of physics and applied physics at Stanford University and a member of Q-NEXT, uses quantum squeezing in his work developing .

Q-NEXT is a U.S. Department of Energy (DOE) National Quantum Information Science Research Center led by DOE’s Argonne National Laboratory. Center researchers use quantum squeezing to make better measurements of quantum systems.

New qubit circuit enables quantum operations with higher accuracy

Posted by in categories: quantum physics, supercomputing

In the future, quantum computers may be able to solve problems that are far too complex for today’s most powerful supercomputers. To realize this promise, quantum versions of error correction codes must be able to account for computational errors faster than they occur.

However, today’s quantum computers are not yet robust enough to realize such error correction at commercially relevant scales.

On the way to overcoming this roadblock, MIT researchers demonstrated a novel superconducting qubit architecture that can perform operations between qubits—the building blocks of a quantum computer—with much greater accuracy than scientists have previously been able to achieve.

New Method Detects Deep Fakes With 99% Accuracy

Posted by in category: computing

A team of computer scientists at UC Riverside has developed a new method to detect manipulated facial expressions in deep fake videos. The method could detect these expressions with up to 99% accuracy, making it more accurate than the current state-of-the-art methods.

The new research paper titled “Detection and Localization of Facial Expression Manipulations” was presented at the 2022 Winter Conference on Applications of Computer Vision.

Can We Ever Adopt a Scalable Water-From-Air Device?

Posted by in category: futurism

Believe it or not, air contains as much water as six times the world’s rivers combined.

This is mostly in the form of water vapor, and it actually replenishes naturally every 8 to 10 days — give or take. This offers a valuable potential reservoir of freshwater that could be tapped relatively easily.

All we need is the right kind of technology.

ChatGPT’s Choices: Overload or Overjoyed? Decoding Decision Dynamics

Posted by in category: robotics/AI

Summary: Researchers delved into how ChatGPT influences user decision-making, focusing on the ‘choice overload’ phenomenon. This condition emerges when an individual is overwhelmed by numerous options, often leading to decision paralysis or dissatisfaction.

The study found, however, that users preferred larger numbers of recommendations from ChatGPT over those from humans or online agents, appreciating the perceived accuracy of the chatbot’s suggestions. This points towards a new paradigm where AI-generated options might enhance decision-making processes across various industries.
