MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

This AI Learned the Laws of Physics and Could Accelerate Quantum Computing Breakthroughs

Researchers in Sweden have developed a machine-learning approach that embeds the laws of physics directly into neural networks.

We have 4 fundamental forces of nature. 'Quantum gravity' could help lead us to a mysterious 5th

Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Quantum computer at Oak Ridge National Lab opening new doors in research

OAK RIDGE, Tenn. (WATE) – Oak Ridge National Laboratory is welcoming a quantum computer, that outperforms the most powerful supercomputers by using the principles of quantum mechanics. Quantum computers can multitask, performing multiple calculations at once instead of solving each problem one at a time, enabling researchers to solve complex equations with greater efficiency than […]

A quantum state that lasts forever may finally be within our grasp

Defying the laws of thermodynamics, experiments are beginning to show that a quantum state that is frozen forever might not be impossible. If we can tame it, it could unlock whole new types of matter

Physicists Create a New Kind of Schrödinger’s Cat State From Exotic Quantum Building Blocks

Oxford physicists have created an unconventional class of quantum superpositions from highly nonclassical states.

Tell HN: Musk doesn't "have" a Trillion, he has the leverage

I wish a competent economist could blog that Musk (and the other uber rich) don't have liquid cash to pile up on their yacht the way the graphics imply.Even the act of selling his stake in tesla and X and spacex would alter the value of the holdings, alter the tax income for some nation state, the act of printing the money would in turn demand time and effort, shipping the money would incur costs.Having the effective influence over investment disposition of $1T is amazing but it isn't

MIT Open Learning reaches all the way to the South Pole

From the icy expanse of the South Pole, John Della Costa, a researcher on the Background Imaging of Cosmic Extragalactic Polarization (BICEP) project, watches STS.042/8.225 (Einstein, Oppenheimer, Feynman: Physics in the 20th Century), a free online class from MIT Open Learning’s OpenCourseWare, as part of a weekly “Fysics Fridays” series he started with his team.MIT Professor David Kaiser, who teaches the course, often receives thoughtful notes from remote learners, but says an email from Della

Quantum Hall effect gains a new twist in graphene moiré systems

Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical counterpart, the nonlinear version can arise even without breaking time-reversal symmetry, and its magnitude is tied to deep geometric properties of electron wave functions. So far, however, the behavior of the effect when a magnetic field is applied has remained poorly underst

Superconductivity breakthrough could unlock ultra-efficient electronics

A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields.

New plasma trick could unlock smaller, more powerful computer chips

A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials. Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma processing. The result is a cleaner, more controlled path toward smaller and more capable electronics.

Ask HN: What are some good/fast coding models for Apple Silicon?

I have an M4 Max with 128 GB of unified memory, and I thought it would be easy to reach decent inference speeds with it. After a few failed attempts to exceed about 150 t/s with completely custom Metal inference engines tailor-built by Claude, I'm stumped.I'm not really sure how to make this hardware usable -- I can only really afford DeepSeek levels of pricing right now, but DeepSeek is slow and I'm really itching for something faster. Up until now, I've had a $200 per

Quantum hyperdimensional computing can work 500 times faster than other methods

Cleveland Clinic researchers are unlocking quantum computing's full potential through the creation of a new computing paradigm inspired by the human brain. Fabio Cumbo, Ph.D., research associate in the lab of Daniel Blankenberg, Ph.D., associate staff, Computational Life Sciences, is developing the model, called quantum hyperdimensional computing (QHDC).

High degree of quantum entanglement detected for first time in centimeter-sized crystal of strange metal

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles? Can they, too, display effects that provide a direct glimpse into the quantum world?

Scientists found a way to explain bird flocks that “defy” Newton’s third law

Physicists have solved a long-standing problem involving systems that appear to violate Newton’s third law, such as bird flocks and bacterial swarms. By adding carefully designed “imaginary partners” to their models, they can now simulate these complex systems with unprecedented accuracy.
