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

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.

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

<p>Nature, Published online: 02 April 2026; <a href="https://www.nature.com/articles/d41586-026-01054-1">doi:10.1038/d41586-026-01054-1</a></p>Two analyses suggest that quantum computers could crack ubiquitous security keys and cryptocurrencies before the decade is over.

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.
