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

Ask HN: Best LLM model for a RAG-based Android app across all smartphones?

I am developing RAG based android app using llama.cpp. For offline processing I am using Qwen 1.5 2.5B model using Q4 quantization, I am offloading computation to GPU if present, However for low end android phones my android app is either crashing due to OOM or If not crashing and no GPU available in that case it takes lots of time to generate text. I also tried with SmolLM 135M model for low end devices but it struggle to follow instruction very well.In this case I am considering openAI API for

Fixed a llama.cpp bug silently disabling Vulkan GPU on all 32-bit ARM devices

While running llama.cpp on a Samsung Galaxy Watch 4 Classic (armeabi-v7a, Mali G68), I noticed the Vulkan backend was rejecting every quantized MUL_MAT operation despite reporting "33/33 layers offloaded to GPU".Root cause: a missing block size division in tensor stride calculation inside create_tensor() in llama-model-loader.cpp. The wrong stride cascades into ggml_nbytes() overflow, exceeding max_buffer_size on 32-bit where size_t is 32-bit.On 64-bit devices the overflow is sile

Five Ways Quantum Technology Could Shape Everyday Life

With billions invested and prototypes being tested outside the lab, the quantum era is starting to take shape. The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop “the world’s most powerful commercial quantum computer” mark just two of the latest developments in quantum technology’s increasingly rapid transition from experimental breakthroughs to practical applications.There is growing promise of quantum technology’s ability to solve problems that today’s system

Electrons in moiré crystals explore higher-dimensional quantum worlds

The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up and down to light up every floor of every building. But the electrons in newly discovered “moiré crystals” move in much stranger ways. They can move left and right, back and forth, or up and down in our three-dimensional world, but these electrons also act as if they can teleport in and out of a mysterious fourth dimens

New Advances Bring the Era of Quantum Computers Closer Than Ever

Some 30 years ago, the mathematician Peter Shor took a niche physics project — the dream of building a computer based on the counterintuitive rules of quantum mechanics — and shook the world. Shor worked out a way for quantum computers to swiftly solve a couple of math problems that classical computers could complete only after many billions of years. Those two math problems happened to be the…Source

A tiny detector for microwave photons could advance quantum tech

Detecting a single particle of light is hard; detecting a single microwave photon is even harder. Microwave photons, the tiny packets of electromagnetic radiation used in current technologies like Wi-Fi and radar, carry far less energy than visible light. They are about 100,000 times weaker than optical photons.

Small quantum system outperforms large classical networks in real-world forecasting

Can a handful of atoms outperform a much larger digital neural network on a real-world task? The answer may be yes. In a study published in Physical Review Letters, a team led by Prof. Peng Xinhua and Assoc. Prof. Li Zhaokai from the University of Science and Technology of China of the Chinese Academy of Sciences demonstrated that a quantum processor comprising just nine interacting spins outperforms classical networks with thousands of nodes in realistic weather forecasting tasks.

IBM quantum processor achieves highest fidelity calculations for the longest period of time on record

Scientists have developed a novel approach to error correction that resulted in the highest-ever fidelity of entangled, logical qubits on a superconducting quantum processor.

The secrets of black holes and the Higgs mass could be hidden in a 7-dimensional geometry

One of the greatest mysteries of modern physics, the "black hole information paradox," might have finally found an elegant solution, and the answer could also reveal the origins of the mass of fundamental particles.

Quantum coherence could be preserved at large scales in realistic environments

Quantum states are notoriously fragile, and can be destroyed simply through interactions, measurements, and exposure to their surrounding environments. In a new theoretical study published in Physical Review X, Rohan Mittal and colleagues at the University of Cologne have discovered a new way to protect quantum behavior on large scales within systems driven far from equilibrium. Their results could have promising implications for the design of more robust quantum devices.

Show HN: WayInfer – Native GGUF engine that runs models larger than your RAM

We built a native inference engine that runs quantized LLMs directly from SSD using memory-mapped I/O. The model never fully loads into RAM — the OS pages weights on demand as each layer executes.*What it does:* - Mixtral 8x22B (80GB, 141B params) runs on a machine with 48GB RAM - Model loads in 0.3 seconds (vs 190s with llama.cpp) - Produces correct output: "What is 2+2?" → "The sum of 2 and 2 is 4." - Zero dependencies — custom tensor engine, custom GGUF parser, no ggm

Show HN: Open-source distributed quantum compute network

Hey HN. I'm Colton (YC S21, ex-Acorns), one of the founders of Postquant Labs. My cofounder Richard is a cryptographer out of Draper Labs and DARPA. We're building Quip.Network, the first distributed quantum compute network. We just opened our testnet and wanted to share it here.The basic problem: quantum hardware is here and already competitive on certain optimization problems, but for most people, there's no way to access it. The machines cost millions and the hardware and resea

Scientists reveal hidden interface in superconducting qubit material

Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and DOE's Pacific Northwest National Laboratory (PNNL) have uncovered an unexpected interface layer that may be ...

SpaceX Starship could slash travel time to Uranus in half

A new concept suggests SpaceX’s Starship could revolutionize a future mission to Uranus, one of the solar system’s most overlooked planets. By refueling in orbit and helping slow the spacecraft on arrival, it could cut travel time nearly in half. That’s a big deal for a mission that would otherwise take over a decade just to arrive. If it works, it could finally open the door to studying this strange, tilted world up close.

The Mad Scramble to Power AI Is Rewiring the US Grid

With data center power demand expected to nearly triple by 2030, tech companies are bankrolling new plants and even their own “shadow grid.” Unless you’ve had your head in the sand, you’re likely aware that AI has a major energy problem. And as AI companies scramble to source power for their ever-expanding fleet of data centers, the technology is reshaping the US grid.After more than a decade of flat growth, nationwide electricity demand has been climbing 1.7 percent annually s

‘It’s a real shock’: quantum-computing breakthroughs pose imminent risks to cybersecurity

Quantum entanglement between electrons and ions captured at attosecond timescale

Quantum mechanics is extremely successful at describing the behavior of matter at the atomic level. This success forces one to accept that certain aspects of physical reality go far beyond our intuition. Among these, none is more intriguing than the concept of quantum entanglement, which mathematically describes how two particles that have at some point in the past interacted with each other retain a memory of this interaction to such an extent that acting on one of the two particles has a measu

Laser-powered wireless hits 360 Gbps and uses half the energy of Wi-Fi

A new breakthrough in wireless technology could dramatically boost internet speeds while cutting energy use—by switching from radio waves to light. Researchers have developed a tiny chip packed with dozens of miniature lasers that can transmit massive amounts of data simultaneously, reaching speeds over 360 gigabits per second in early tests.
