Creating quantum-entangled networks of atomic clocks and accelerometers

Posted by in categories: particle physics, quantum physics

Researchers affiliated with the Q-NEXT quantum research center show how to create quantum-entangled networks of atomic clocks and accelerometers—and they demonstrate the setup’s superior, high-precision performance.

For the first time, scientists have entangled atoms for use as networked , specifically, atomic clocks and accelerometers.

The research team’s experimental setup yielded ultraprecise measurements of time and acceleration. Compared to a similar setup that does not draw on , their time measurements were 3.5 times more precise, and acceleration measurements exhibited 1.2 times greater precision.

Researchers At Stanford Have Developed A New Artificial Intelligence (AI) Benchmark To Understand Large Language Models (LLMs)

Posted by in category: robotics/AI

Benchmarks orient AI. They encapsulate ideals and priorities that describe how the AI community should progress. When properly developed and analyzed, they allow the larger community to understand better and influence the direction of AI technology. The AI technology that has evolved the most in recent years is foundation models, highlighted by the advent of language models. A language model is essentially a box that accepts text and generates text. Despite their simplicity, these models may be customized (e.g., prompted or fine-tuned) to a wide range of downstream scenarios when trained on vast amounts of comprehensive data. However, there still needs to be more knowledge on the enormous surface of model capabilities, limits, and threats. They must benchmark language models holistically due to their fast growth, growing importance, and limited comprehension. But what does it mean to evaluate language models from a global perspective?

Language models are general-purpose text interfaces that may be used in various circumstances. And for each scenario, they may have a long list of requirements: models should be accurate, resilient, fair, and efficient, for example. In truth, the relative relevance of various desires is frequently determined by one’s perspective and ideals and the circumstance itself (e.g., inference efficiency might be of greater importance in mobile applications). They think that holistic assessment includes three components:

AI invents millions of materials that don’t yet exist

Posted by in categories: information science, robotics/AI

UC San Diego nanoengineering professor Shyue Ping Ong described M3GNet as “an AlphaFold for materials”, referring to the breakthrough AI algorithm built by Google’s DeepMind that can predict protein structures.

“Similar to proteins, we need to know the structure of a material to predict its properties,” said Professor Ong.

“We truly believe that the M3GNet architecture is a transformative tool that can greatly expand our ability to explore new material chemistries and structures.”

Cell-based therapies for neurological disorders — the bioreactor hypothesis

Posted by in category: biotech/medical

In this Review, Savitz and Cox consider the evidence for a model of cell-based therapy referred to as the bioreactor hypothesis, in which exogenous cells migrate to peripheral organs and reprogramme host immune cells to generate an anti-inflammatory, regenerative environment.

Elon Musk says Twitter is recruiting just weeks after laying off half the company’s staff

Posted by in category: Elon Musk

Since then, the tech mogul and Tesla CEO has let further staff go, some through layoffs aimed at downsizing the company and others through more targeted firings.

But after scrambling to get rid of staff, Twitter is still now actually hiring, Musk said in a presentation to the company, slides from which he posted on Twitter.

“We’re recruiting,” the slide simply read.

Rolls-Royce tests hydrogen-fueled aircraft engine in aviation world first

Posted by in categories: energy, government, military

British engineer Rolls-Royce has successfully used hydrogen instead of conventional jet fuel to power a modern aircraft engine in a world first for the aviation industry, according to the company.

The ground test, which took place at a government test facility at Boscombe Down, used green hydrogen generated by wind and tidal power from the Orkney Islands in Scotland.

Rolls-Royce used a converted AE 2100-A turboprop engine that powers civil and military aircraft to conduct the test in partnership with easyJet.

In a first, Rolls-Royce and easyJet successfully test a hydrogen-powered aircraft engine

Posted by in categories: energy, transportation

The test is a stepping stone to achieving carbon neutrality by 2050.

In what can be considered a promising first step towards transforming the aviation industry to become carbon-neutral, a project led by Rolls Royce and easyJet has successfully tested a modern-day jet engine that runs solely on hydrogen.

The prototype for the experiment, which was conducted at a test facility at the Ministry of Defence Boscombe Down, U.K., was a commonly-used Rolls-Royce AE-2100A regional aircraft engine. The turbine was supplied with ‘green’ hydrogen, which was made by splitting water into its constituent components at European Marine Energy Centre in the Orkney Islands, U.K.
