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
New monolithic ion trap opens quantum simulations to more researchers
Some quantum systems are so complex that even the most powerful supercomputers struggle to simulate their behavior. One solution is quantum simulation: building a controllable quantum system in the lab and tuning it to mimic the one researchers want...
A new way to detect stabilizing properties of optical devices
In optical fibers, chips and other light-guiding devices, minor defects can scatter photons and disrupt their path. A new study demonstrates a way to reveal properties which, in certain systems, help light wave behavior withstand such flaws. The meth...
Physicists prove a long-suspected quantum speed limit for thermalization
Whether we are waiting for a car windshield to defrost in winter or a warm drink to cool down, how long it takes for an object to settle into a stable, even temperature within its environment (thermal equilibrium) depends on numerous factors. These c...
Ask HN: What Got You into Rust?
Back in 2024 I was experimenting with prosthetic arms and trying to figure out how to build one with an EMG sensor. The problem I kept running into was that the EMG sensor kept crashing the Arduino IDE. It spat out data at an extremely high rate, and...
Physicists create a bizarre new quantum state called a fractional fermi sea
Physicists have discovered a strange new state of quantum matter in which ultracold atoms defy familiar organizational rules, forming a highly excited yet surprisingly orderly configuration called a "fractional Fermi sea." The discovery challenges es...
Hybrid diamond chip strengthens interactions between light and quantum bits
Researchers have developed and demonstrated a new hybrid photonic platform that integrates quantum emitters with photonic devices, providing a way to reliably control the interaction between photons and quantum information carriers. The chip-based pl...
Two monster black holes could collide in just 100 years
Astronomers have uncovered compelling evidence of two supermassive black holes spiraling toward a potentially spectacular collision at the center of galaxy Mrk 501. A previously unseen jet of particles revealed the likely presence of a second black h...
Scientists who discovered a third form of magnetism win major physics prize
Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in qua...

A new communication framework called PQ-NeuroLink brings post-quantum cryptography to distributed EEG brain-computer ...
Prediction: This Will Be the Best Pure-Play Quantum Computing Stock Over the Next 5 Years
Quantum computing is developing quicker than most investors realize. For a long time, 2030 was the year that most quantum ...
Analyst warns of 'smaller' gap after Google's quantum breakthrough
Google says its latest breakthrough takes it another step closer to building a useful, error-corrected quantum computer.
Google's quantum computer just achieved a major breakthrough with 'magic states'
Quantum computers have an inconvenient problem: they're magnificently efficient at making mistakes. These marvelous machines ...
NASA’s SpaceX launch lights up the sky with a giant glowing jellyfish
A SpaceX Falcon 9 rocket created a dazzling, jellyfish-shaped glow across the eastern United States as sunlight illuminated its exhaust during an early morning launch. The mission delivered equipment and scientific experiments to the International Sp...

Claude’s new quantum circuit design uses 17 times fewer gates than earlier approach
Anthropic’s Claude Mythos 5 has developed a quantum circuit design that uses 17 times ...
Silicon spin qubits reach 99.99% fidelity bringing larger quantum processors into reach
A five-qubit silicon experiment tackles microwave interference, helping quantum processors work accurately in parallel.
Show HN: Netsat, a shared internet virtual satellite you can use to learn DSP
Receiving and decoding satellites is (in my opinion) one of the coolest things you can do with a radio. The problem is that it has a steep learning curve. Protocols are complicated, signals are hard to catch and track, and requires an investment in e...
Ask HN: Not sure but maybe that's why we all do coding
As a programmer, you must have came across the word AI.
(As I'm a new user here, please read it atleast once, as I'll explain an interesting test on myself... The UI hurts, but feels cool though)It can easily do whatever task you give it,...
Quantum magic state cleanup cuts errors 40-fold in first successful hardware test
Qubits, the quantum equivalent of digital bits, are fragile and prone to errors. That makes building reliable quantum computers extremely difficult. One fix has been to use traditional magic state distillation, which filters out flaws, but it is extr...
