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

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

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.

Knock, knock... mapping comedic timing with a computational framework

Researchers propose a computational method to reveal the hidden timing structure of live performance. Vanessa C. Pope and colleagues present a framework, called Topology Analysis of Matching Sequences (TAMS), that algorithmically detects repeated material across performances and maps its timing to visualize performance dynamics. The work is published in PNAS Nexus.

A faint signal from the Universe’s dark ages could reveal dark matter

After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this signal could be slightly altered by dark matter, leaving behind a measurable fingerprint. Future radio telescopes on the Moon may be able to detect it and shed light on one of astronomy’s greatest mysteries.

James Webb catches an exoplanet losing its atmosphere in real time

Astronomers have captured the most dramatic view yet of a planet losing its atmosphere, watching the ultra-hot gas giant WASP-121b for an entire orbit with the James Webb Space Telescope. Instead of a single stream of escaping gas, the planet is wrapped in two colossal helium tails—one trailing behind like a comet, the other stretching ahead toward its star.

An electrically powered source of entangled light on a chip

Quantum technologies are cutting-edge systems that can process, transfer, or store information leveraging quantum mechanical effects, particularly a phenomenon known as quantum entanglement. Entanglement entails a correlation between two or more distant particles, whereby measuring the state of one also defines the state of the others.

New quantum boundary discovered: Spin size determines how the Kondo effect behaves

Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, they produce unique effects not seen in individual particles. Understanding how quantum spins interact to produce this behavior is central to modern condensed-matter physics.
