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

How long do you think? I give it 3 years

Who’s ready here? I feel like in 3 years time we are being forced out into retirement.I already replaced the junior devs I work with entirely, soon I’ll be replaced.A few years back actually, before AI as we know it, there were lots of quants in finance making millions who now are algo bots that cost in the hundreds of thousands but still lot less than millions in commission (plus no sick day, etc, etc).You get the point, I’m not asking “if” I’m asking “when”. What’s your take on the question? I

Meta Will Buy Startup’s Nuclear Fuel in Unusual Deal to Power AI Data Centers

The company, Oklo, plans to use the fuel at a 1.2-gigawatt plant in Ohio that’s due as early as 2030. As data-center energy bills grow exponentially, technology companies are looking to nuclear for reliable, carbon-free power. Meta has now made an unusually direct bet on a startup developing small modular reactor technology by agreeing to finance the fuel for its first reactors.The nuclear industry’s flagging fortunes have rebounded in recent years as companies like Google, Amazon, and Mic

Scalable quantum computers closer to reality with new ultra-fast photonic chips

German scientists have laid the groundwork for the next generation of quantum technologies by developing an ultra-fast, ultra ...

Cobalt honeycomb magnet shows how quantum spin liquids might be engineered

A restless state, known as a quantum spin liquid, could unlock new kinds of particles and serve as a foundation for quantum ...

Unbreakable? Researchers warn quantum computers have serious security flaws

Quantum computers could revolutionize everything from drug discovery to business analytics—but their incredible power also makes them surprisingly vulnerable. New research from Penn State warns that today’s quantum machines are not just futuristic tools, but potential gold mines for hackers. The study reveals that weaknesses can exist not only in software, but deep within the physical hardware itself, where valuable algorithms and sensitive data may be exposed.

Positronium shows wave behavior for first time, confirming quantum theory prediction

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

RGTI and QUBT: This Analyst Sees the Next Jump in Quantum Stocks

Quantum computing is the latest shiny thing in tech, a new technology operating at the leading edge of the computer industry. It leverages the natural superposition properties of subatomic physics to enable faster rates of calculation; instead of the 0–1 states of binary systems, quantum computers can operate in both positions simultaneously, allowing for faster computing times and higher-density information storage. The demand for that kind of computing power is only accelerating. From biopharm

Show HN: Cluster-Computing for Python Beginners

Hi HN, I'm a co-founder of Burla.dev, we're building cluster compute software for Python beginners. . We help people in Biotech, Geospatial, and quant-finance scale their analyses in the cloud without help from other engineering teams. . There are many fields where people code daily and deal with lot's of data, yet specialize in something other than engineering. We built Burla to enable these people to process massive amounts of data completely on their own. Our python pac

To flexibly organize thought, the brain makes use of space

Our thoughts are specified by our knowledge and plans, yet our cognition can also be fast and flexible in handling new information. How does the well-controlled and yet highly nimble nature of cognition emerge from the brain’s anatomy of billions of neurons and circuits? A study by researchers in The Picower Institute for Learning and Memory at MIT provides new evidence from tests in animals that the answer might be found within a theory called “spatial computing.”First proposed in 2023 by

It started with a cat: How 100 years of quantum weirdness powers today's tech

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum computers and secure communications.

A twitch in time? Quantum collapse models hint at tiny time fluctuations

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at once, defined mathematically by what physicists call a "wavefunction." But this runs counter to our everyday experience of objects that are either here or there, never both at the same time.

New method reveals quantum states using indirect measurements of particle flows

A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

Direct visualization captures hidden spatial order of electrons in a quantum material

The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST researchers have succeeded in directly observing the moments when electrons form and dissolve ordered patterns.
