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
Supercurrent enables the reading of quantum information without destroying it
One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a ...
Watch the universe emerge from the dark ages, with Lumina
With the Big Bang, the universe burst into existence as a hot and dense soup of electrons and subatomic particles. This primordial ionized plasma, initially smaller than a single atom, rapidly expanded and cooled. In the process, particles in the sou...
Show HN: Comparing SF Bay Area trash rates
I created this webpage to compare the rates for trash hauling across the San Francisco Bay Area.I wanted to see how Oakland California compares to the rest of the region. I knew the rates were high, but I wanted to quantify how high. Especially since...
Show HN: Find overlapping Rust tests with mutation testing
To tackle the ever-increasing number of tests, I built cargo-test-prune.The idea behind it is to use cargo-mutants to generate mutants, and then solve the set cover problem for those mutants to suggest which tests can be eliminated.
(use a greedy alg...
Scientists overcome a hidden obstacle to more powerful quantum computers
Scientists have discovered a way to operate multiple silicon qubits simultaneously with remarkable accuracy, overcoming a major challenge in scaling up quantum computers. Their new technique maintained accuracy of approximately 99.9% even when all fi...
Nvidia CEO Jensen Huang says quantum computers could help train AI
Nvidia CEO Jensen Huang says quantum computers could help train AI by simulating biology and chemistry and generating ...
The insane mechanism of a quantum computer?
Part 1 of a (at least) 2-part series on quantum computing. Chapters: 0:00 - Quantum Computers 0:55 - Common computer ...
Quantum computers can get colder than deep space — Here's how they stay running
Quantum computers are kept at temperatures near absolute zero to keep heat from affecting them. Dilution refrigerators ...
Supercurrent enables the reading of quantum information without destroying it
One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically cause...
Quantum study highlights Cornell, Rochester strengths as New York plans $360M investment
A state-commissioned quantum technology study identifies Cornell research and Rochester optics as regional strengths as New York plans $360 million for research and commercialization hubs. Gov. Kathy ...
Chattanooga’s Ambitious Plan To Become America’s Quantum Capital
A bold bet on fiber optics transformed a city. Now a billion-dollar opportunity in quantum technologies could reshape its ...
A lost Schrödinger manuscript reveals a surprising twist in quantum physics
Physicist Erwin Schrödinger in 1933. (National Digital Archives, Poland/Public Domain) For more than 80 years, a manuscript ...
Physicists may have inadvertently built a qubit that can run backward in time
(Quarta_/iStock/Getty Images Plus) In the classical Universe, the arrow of time flies one way – but in the quantum realm, ...
Three giant black holes discovered in a galaxy from the dawn of time
Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and...

ReVault – new secure archive format
reVault is a new, secure-by-default archive format called a lockbox, designed to be simple to use.I've been working on reVault for about 2 years. It was originally written in Dart, but with the improvements in AI, I decided to port it to Rust us...
Ask HN: Linux at work revoked due to MDM, how to fight?
I'm a software engineer that likes Linux.My employer is going all in on their B2B strategy. We're implementing full mobile device management. I just got news that I will need to hand in my laptop EOY and get a Mac instead.I'm of course...
Show HN: Perch, a calm Mac app for juggling Claude Code sessions
I'm an engineer, but I also hate using tools that make things overcomplicated.It's also tough with the new pace of AI-driven development to really get into the flow state, and maintain (still needed!) focus on 1 thing.So I built a tool that...
Show HN: Visual Studio extension that shows decimal and hex in the debugger
For quite some time I've wanted to write a Visual Studio extension that shows both decimal and hex values while debugging.With Claude Code, I've now been able to make it happen. Name: AlwaysHex.
