Quantum Entanglement May Share a Profound Link With Steam Engines

Posted by in categories: computing, particle physics, quantum physics

A year after all but ruling out the possibility, a pair of theoretical physicists from Japan and the Netherlands have found quantum entanglement has something fundamentally in common with the physics that drives steam engines, dries your socks, and may even keep the arrow of time pointed in one direction.

This universal property, if indeed it exists as they suggest, would govern all transformations between entangled systems and give physicists a way to measure and compare entanglement beyond counting qubits – and know their limits of manipulating entangled pairs.

Quantum entanglement, the tendency for the quantum fuzziness of different objects to mathematically merge, is a fundamental part of quantum computing along with superposition. When particles, atoms, or molecules are entangled, knowing something about one tells us something of the other.

Tim Cook on Generative AI: ‘We Have Advantages That Will Differentiate Us’

Posted by in categories: futurism, robotics/AI

During today’s earnings call covering the second fiscal quarter of 2024, Apple CEO Tim Cook again spoke about Apple’s work on generative AI. He said that Apple has “advantages” that will “differentiate” the company in the era of AI, and some “very exciting things” will be shared with customers in the near future.

We continue to feel very bullish about our opportunity in generative AI. We are making significant investments and we’re looking forward to sharing some very exciting things with our customers soon.

We believe in the transformative power and promise of AI and we believe we have advantages that will differentiate us in this new era, including Apple’s unique combination of seamless hardware, software and services integration, groundbreaking Apple silicon with our industry leading neural engines, and our unwavering focus on privacy, which underpins everything we create.

Astronomers inspect population of young stellar objects in open cluster NGC 346

Posted by in category: cosmology

Using the James Webb Space Telescope (JWST), an international team of astronomers has explored young stellar objects (YSOs) in an open cluster known as NGC 346. The study, published April 24 on the preprint server arXiv, yields crucial information about the properties of YSO population in this cluster.

Experiment opens door for millions of qubits on one chip

Posted by in categories: computing, quantum physics

Researchers from the University of Basel and the NCCR SPIN have achieved the first controllable interaction between two hole spin qubits in a conventional silicon transistor. The breakthrough, reported in Nature Physics (“Anisotropic exchange interaction of two-hole spin qubits”), opens up the possibility of integrating millions of these qubits on a single chip using mature manufacturing processes.

The race to build a practical quantum computer is well underway. Researchers around the world are working on a huge variety of qubit technologies. So far, there is no consensus on what type of qubit is most suitable for maximizing the potential of quantum information science.

At the Edge of Explosion: How New Science Is Making Old Reactions Safer

Posted by in categories: chemistry, science

The chemical industry has been using a reaction with explosive chemicals for over 100 years — now Mülheim scientists have discovered a safer alternative.

Explosions and poisoning. Serious injuries and even deaths. In the history of the chemical industry, there have been repeated accidents, sometimes fatal, often caused by dangerous and explosive chemicals that are required for certain reactions.

Aryldiazonium salts, which have been used for 140 years, are such chemicals. They are very reactive and therefore extremely useful for producing other compounds – dyes, for example. However, the high reactivity means that isolated aryldiazonium salts are not very stable and can therefore react unintentionally and sometimes explosively. On December 23, 1969, there was a particularly serious explosion involving these chemicals at Ciba AG in Basel. A building was destroyed and heavy pieces of the reactor flew through the air. Three workers lost their lives and 31 were seriously injured. Despite such horrific reports, work continues with aryldiazonium salts.

Quantum Leap: How a New Experiment Could Solve Gravity’s Biggest Mystery

Posted by in categories: particle physics, quantum physics

A proposed experiment shows that quantum entanglement is not the only way to test whether gravity has a quantum nature.

Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum mechanics. Until now, all experimental proposals to answer this question have relied on creating the quantum phenomenon of entanglement between heavy, macroscopic masses. But the heavier an object is, the more it tends to shed its quantum features and become ‘classical’, making it incredibly challenging to make a heavy mass behave as a quantum particle. In a study published in Physical Review X, researchers from Amsterdam and Ulm propose an experiment that circumvents these issues.

Classical or Quantum?

Intense Solar Flare Captured by NASA’s Solar Dynamics Observatory

Posted by in category: alien life

The Sun emitted a strong solar flare, peaking at 10:22 p.m. ET on May 2, 2024. NASA ’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Solar flares are intense bursts of radiation emanating from the release of magnetic energy associated with sunspots. These flares are among the biggest explosive events in our solar system, visible primarily in the ultraviolet range.

Flares impact Earth in a variety of ways: they can disrupt the ionosphere and interfere with GPS navigation and radio communications. They are also responsible for auroras, the beautiful natural light displays often seen in high-latitude skies.
