Claude 2: We are pleased to announce Claude 2, our new model

Posted by in categories: business, education, mathematics

We are pleased to announce Claude 2, our new model. Claude 2 has improved performance, longer responses, and can be accessed via API as well as a new public-facing beta website, claude.ai. We have heard from our users that Claude is easy to converse with, clearly explains its thinking, is less likely to produce harmful outputs, and has a longer memory. We have made improvements from our previous models on coding, math, and reasoning. For example, our latest model scored 76.5% on the multiple choice section of the Bar exam, up from 73.0% with Claude 1.3. When compared to college students applying to graduate school, Claude 2 scores above the 90th percentile on the GRE reading and writing exams, and similarly to the median applicant on quantitative reasoning.

Think of Claude as a friendly, enthusiastic colleague or personal assistant who can be instructed in natural language to help you with many tasks. The Claude 2 API for businesses is being offered for the same price as Claude 1.3. Additionally, anyone in the US and UK can start using our beta chat experience today.

Microsoft’s Automatic Prompt Optimization Improves Prompts to Boost LLM Performance

Posted by in category: robotics/AI

The recent rise of powerful large language models (LLMs) has revolutionized the field of natural language processing (NLP).

The performance of these generative models is largely dependent on users’ prompts, which are becoming increasingly detailed and complex.

A Google Trends search reveals a hundredfold increase in popularity for the term “prompt engineering” over the last six months, and social media is teeming with novel prompting tips and templates.

The Biggest Telescope in the World is Half Built

Posted by in categories: space, sustainability

The European Southern Observatory continues to build the largest telescope in the world, the Extremely Large Telescope (ELT). Construction of the telescope began in 2014 with flattening the top of a mountain named Cerro Armazones in Chile’s Atacama Desert.

ESO just announced that progress on construction has crossed the 50% mark. The remaining work should take another five years. When it finally comes online in 2028, the telescope will have a 39-meter (128 ft) primary mirror of 798 hexagonal segments, making it the largest telescope in the world for visible and infrared light. The new telescope should help to answer some of the outstanding questions about our Universe, such as how the first stars and galaxies formed, and perhaps even be able to take direct images of extrasolar planets.

Reinventing cosmology: uOttawa research puts age of universe at 26.7 — not 13.7 — billion years

Posted by in categories: cosmology, physics

Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.”

“Our newly-devised model stretches the galaxy formation time by a several billion years, making the universe 26.7 billion years old, and not 13.7 as previously estimated,” says author Rajendra Gupta, adjunct professor of physics in the Faculty of Science at the University of Ottawa.

For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming from distant galaxies. In 2021, thanks to new techniques and advances in technology, the age of our universe was thus estimated at 13.797 billion years using the Lambda-CDM concordance model.

Ammonia, chemically written as NH3, is widely used across industries ranging from textiles to pharmaceuticals and is an important component in the manufacture of fertilizers. For its current use, ammonia is stored in pressure-resistant containers after liquefying it at temperatures of-27 Fahrenheit (−33 degrees Celsius).

Superconducting qubit foundry accelerates progress in quantum research

Posted by in categories: government, quantum physics

Advancing the state of the art in superconducting qubit hardware requires knowledge across a range of disciplines, including materials, fabrication, circuit design and simulation, packaging, cryogenics, low-noise measurement, hardware-software interfacing, and quantum compilation. As understanding of materials and processes has advanced over time, fabricating the highest-quality qubits increasingly relies on millions of dollars of fabrication equipment and countless hours of process development and sustainment.

“It has become increasingly challenging for individual organizations to maintain this full stack of expertise, particularly as circuits become more complex to design, fabricate, and measure,” Schwartz says. “As a result, superconducting qubit hardware research has remained centralized into a relatively small number of laboratories and large universities capable of developing and sustaining this expertise.”

MIT Lincoln Laboratory is one of these laboratories, with more than 20 years of research and development in superconducting qubits and demonstrations of world-leading qubit performance. The qubits are made on-site at the Microelectronics Laboratory, considered to be one of the U.S. government’s most advanced foundries, and in specialized prototyping facilities. The collective expertise and equipment of this facility have made it possible to stand-up the SQUILL Foundry.

Physicists measure electron’s ‘topological spin’

Posted by in categories: particle physics, quantum physics

An international team of physicists has succeeded in measuring a property of the electron known as topological spin winding for the first time. The team obtained this result by studying the behaviour of electrons in so-called kagome metals, which are materials that have unique quantum properties related to their physical shape, or topology. The work could advance our understanding of the physics of superconductors and other systems that contain strongly correlated electrons.

Kagome metals are named after a traditional Japanese basket-weaving technique that produces a lattice of interlaced, symmetrical triangles with shared corners. When the atoms of a metal or other conductor are arranged in this kagome pattern, their electrons behave in unusual ways. For example, the wavefunctions of the electrons can interfere destructively, resulting in highly localized electronic states in which the particles interact strongly with each other. These strong interactions lead to a range of quantum phenomena, including magnetic ordering of unpaired electrons spins that can produce, for example, ferro-or antiferromagnetic phases, superconducting structures, quantum spin liquids and abnormal topological phases. All these phases have applications in advanced nanoelectronics and spintronics technologies.

In the new work, researchers led by Domenico Di Sante of the University of Bologna in Italy studied the spin and electronic structure of XV6Sn6, where X is a rare-earth element. These recently-discovered kagome metals contain a Dirac electronic band and a nearly flat electronic band. At the point at which these bands meet, an effect called spin-orbit coupling creates a narrow gap between the bands. This spin-orbit coupling also creates special type of electronic ground state at the material’s surface.

IBM mulls using its own AI chip in new cloud service to lower costs

Posted by in categories: business, robotics/AI

SAN FRANCISCO, July 11 (Reuters) — International Business Machines (IBM) (IBM.N) is considering the use of artificial intelligence chips that it designed in-house to lower the costs of operating a cloud computing service it made widely available this week, an executive said Tuesday.

In an interview with Reuters at a semiconductor conference in San Francisco, Mukesh Khare, general manager of IBM Semiconductors, said the company is contemplating using a chip called the Artificial Intelligence Unit as part of its new “watsonx” cloud service.

IBM is hoping to take advantage of the boom in generative AI technologies that can write human-like text more than a decade after Watson, its first major AI system, failed to gain market traction.
