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

Show HN: Three backtested quant strategies as Jupyter notebooks

I've spent a few years building quant strategies and most of the work isn't the math — it's the plumbing: getting clean data, structuring the backtest so it doesn't look at the future, generating a readable tearsheet. I packaged three of my working strategies as self-contained notebooks so someone can go from zero to a proper backtest in an afternoon.The three strategies:1. Funding Rate Carry — Goes long assets with consistently negative funding (market paying you to hold) wh

Show HN: Quant Job Market Visualizer

Inspired by karpathy's US job market visualizer[0], I started to dabble with the idea of building live dashboards for certain job markets, starting with quant finance. I extract the career pages of pretty much every major quant firm and classify each posting with a lightweight LLM ETL pipeline. The data is updated daily and the full dataset is available as SQLite for anyone who wants to do their own analysis.[0] https://karpathy.ai/jobs/

IonQ (IONQ) Stock Surges 16% on Major DARPA Quantum Computing Deal

IonQ (IONQ) stock rallies 16% to $34.56 after winning DARPA quantum contract, advancing scalable networks and hybrid quantum ...

France bets €500 million that quantum computing is the tech race Europe can finally win

Five French startups are competing for €500M in government funding to build fault-tolerant quantum computers, with Alice & Bob's cat qubits emerging as a serious contender against US rivals.

One Shot Just Crushed Three Deadly Autoimmune Diseases

A woman battling the conditions went from “two handfuls of pills” and blood transfusions daily to medication-free. The 47-year-old woman was at the end of her rope.In 2014, she was diagnosed with a rare form of anemia. Her body’s B cells, which normally produce antibodies to fight infections, had gone rogue, endlessly attacking oxygen-carrying red blood cells. Two other autoimmune disorders soon followed, one crippling her body’s ability to stop bleeding, the other increasing the ris

Smart cable sharing gives quantum computers a big boost

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases. Researchers at Chalmers University of Technology in Sweden have now demonstrated that several qubits can share the same cable—without significantly increasing computation time. Their study is the most comprehensive of its kind and could become an important piece of the puzzle in developing quantum computers. These computers have the p

A silicon-compatible path toward scalable quantum systems

Beginning in the 1950s, silicon transformed the electronics industry by enabling smaller and faster devices that could be reliably manufactured at scale. More than six decades later, silicon-based semiconductors remain at the heart of many modern technologies, including so-called "classical" computers.

Mirror-positioning method could make quantum gravity tests possible

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where a particle does not have a single definite value of position or momentum until it is measured. A major open question is whether gravity, one of the fundamental forces, also follows the quantum rule. One way to examine this is through gravity-induced entanglement, in which two objects that interact only via gravity become quantum mechanically linked.

Using atomic nuclei could allow scientists to read time more precisely than ever

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.

Quantum simulations tackle photon polarization flip, but today's hardware falls short

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of countless experiments and agreeing with observations down to the smallest known precisions. Yet, some high-intensity scales of QED remain unexplored, prompting some to wonder if quantum computers could deal with these scales' inherent complexity.

Harnessing the fundamental rules of the universe

Tue, 14 Apr 2026 12:00:00 +0000Every April 14, the global quantum community celebrates World Quantum Day. It’s a day that resonates strongly at Waterloo — Canada’s densest cluster of quantum talent, researchers, students and industry partners. Here, they work in close proximity, using the universe’s fundamental rules of quantum science to create new technologies, shaping Waterloo’s Quantum Valley. Tags: Community updates

How Quantum Mechanics Went From Baffling Theory to Revolutionizing Modern Technology

Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Ask HN: What's your experience with PoW captchas against form spam?

Hey folks,I'm building an Open Source email newsletter tool and one of the challenges we have is form spam: As soon as a signup form goes live somewhere, bots will try to sign up. This is possibly an attempt to overwhelm the inbox of people whose accounts have been compromised. But it's also bad for the people who run the newsletter as these ultimately unwanted emails reduce their sender reputation.There was recently a discussion here on HN about this topic [1]. The post author ended u

Ask HN: On autistic spectrum, best way to live?

I've been highly logical and obsessive with reading since early childhood, and I got into programming pretty early and built Flash animation since kindergarten. I've always had issues with my peers and teachers, I got bullied quite often, and it was a source of emotional distress. I felt the constant need to work on things that intrigues me, and I'd read books like encyclopedia, I didn't know that then, but I now suspect myself to be on the spectrum. I believe many in the HN

Show HN: Revdiff – TUI diff reviewer with inline annotations for AI agents

I built a terminal diff viewer for a workflow I couldn't do comfortably with existing tools: reviewing AI-generated code changes without leaving the terminal session where the agent runs, annotating what needs to change, and feeding those annotations straight back to the agent. Plenty of diff viewers exist, and some can even feed notes back to an agent, but none of them fit that flow for me - they pulled me out of the terminal into a separate app, or the round-trip back to the agent was clu

Show HN: Specsight – Living product specs generated from your codebase

Heyy HN, I'm OlaI'm an engineer myself, and everywhere I've worked there was a similar dynamic: someone from the non-technical side of the team (PM, CS, stakeholders) needs to understand what changed recently or how something works today. They rely on stale Confluence pages or ping engineers in Slack and wait. engineers get interrupted daily answering "how does this actually work". it's a mess that gets worse as the team growsor when you join a new company and try t

Show HN: Equirect – a Rust VR video player

This is almost entirely created by Claude, not me. I know some people aren't into that. I was one of them 3 months ago. Since the beginning of the year I finally started getting more serious about trying out AI. The company I work for also had an AI week with lots of training. All I can say is I'm pretty blown away. My entire life feels like it changed over the last month from someone who mostly writes code to mostly someone that prompts AI to write code. And just for a tiny bit of con
