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
Optical experiment demonstrates the strong Mpemba effect in a single qubit
Typically, after a physical system is disturbed, it can gradually return toward a state of thermal equilibrium by exchanging ...
Physicists propose reading a qubit through the tiny supercurrent it makes itself, reaching 99.85% accuracy in simulations
A qubit built from a quantum dot between two superconductors could be read by watching the tiny oscillating supercurrent it ...
Show HN: A visualization map of the funding of public companies
I made this webapp (vibecoded) with Meta's AI models during the Meta AI hackathon that just ended (Oct 26-Nov 4). So far it contains public 33,000 companies, and 100k+ 'flows'. A company X has a flow to another company Y if X funds Y o...
After 40 years, CERN finds evidence of a one-in-10-billion particle decay
CERN scientists have finally found evidence of a particle decay so rare that it happens only once in roughly 10 billion decays, ending a search spanning more than 40 years. The breakthrough could help physicists uncover hidden particles and forces th...
Upgraded microscope can now watch individual quantum particles in motion
Energy can be carried in a number of ways: by electrons, the particles that underpin all modern electronics, as well as by quasiparticles, the results of different particles interacting with one another at the quantum level. Columbia chemist Milan De...

In the first week of November, IBM announced that it had placed its latest quantum computers at a research hub at the ...
IBM deploys Quantum System Two in Chicago, Illinois
The first deployment is located at IBM’s quantum site in Poughkeepsie, New York; the platform sees a 120-qubit IBM Quantum ...
"Observation changes reality." Who is the "observer" in quantum mechanics? | Masahiro Hotta & Katsuhiko Hiroe, "The 'New Common Sense' of Quantum Mechan…
At night, I scroll through my smartphone screen. The phrase "In quantum mechanics, observation changes reality" catches my ...
Extended mathematical language captures symmetry in layered materials
Symmetry is all around us, from the repeating patterns of crystals to the stitches in a knitted sweater. In materials science, these patterns are more than just visually appealing: They can influence how a material conducts heat, transports electrici...
Atomic defects leave telltale optical fingerprints in quantum material
The tiny atomic defects so important for future quantum technologies can be difficult to spot. Fortunately, they leave behind some clues. The defects can alter how a material responds to light, producing a distinctive optical fingerprint that scienti...
Quantum interference keeps two atoms bound despite enough energy to break apart
How can something remain intact when it should naturally break apart? This question has been addressed by researchers at RPTU. Their work has led to the experimental observation of an unusual quantum state in which two atoms remain bound together eve...
The fastest levitated spinning magnet ever made might help physicists search for dark matter
Tiny levitated magnets are able to avoid contact friction, making them useful for detecting extremely weak forces and magnetic fields and acting as ultralow-noise quantum sensors and precision measurement tools. Combining levitation with extreme cold...
The art of good conversation may involve a little pink noise
Most of us like a good old chat with friends, colleagues, neighbors or acquaintances. But what can turn a really good chat into a great one? Sure, conversation topics matter, but scientists have found underlying patterns that may explain our best int...
