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
Quantum computers go high-dimensional with a four-state photon gate
The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it possible to carry out quantum computations on pairs of photons that are each in four different quantum states, or combinations thereof. The advancement is an important milestone for optical quantum computers. The study has now been published in Nature Photonics.
Quantum algorithm beats classical tools on complement sampling tasks
Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers have worked to rigorously demonstrate such advantages, ideally in ways that are provable, verifiable and experimentally realizable.
Why the outer solar system is filled with giant cosmic “snowmen”
Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes could form without violent collisions tearing them apart. Now researchers at Michigan State University have recreated the process in a powerful new simulation, showing that simple gravitational collapse can naturally produce these cosmic “snowmen.”
Young Mars volcano hides a powerful magma engine beneath the surface
A Martian volcano once thought to be the result of a single eruption turns out to have a much more complex past. Orbital imaging and mineral data show it developed through multiple eruptive phases, all powered by the same evolving magma system underground. Shifts in mineral composition reveal the magma changed over time, hinting at different depths and storage histories. Mars’ interior was far more active than previously believed.
Show HN: C++26 Reflection for Python Algo Trading
There’s a constant tension in quant dev between speed-to-market (Python) and speed-to-book (C++). We've had bridges like PyBind11 [1] for years, but the manual boilerplate is usually too high a tax to use them for daily work.With the C++26 Reflection (P2996) [2], that bridge can now be made invisible. That's the new syntax: ^^T and [: x :] .I built this repo to show how you can use the Bloomberg/Clang P2996 fork [3] to automatically reflect a C++ quant engine into a Python execut
Show HN: I built a dependency graph for the tree of human science
Hi HN,
I’ve always been frustrated by this: we live in an era of exponential scientific progress, but almost no one can clearly trace a cutting-edge discovery back to the first principles it’s built on. We learn science in silos, not as a connected, logical tree.
So I built The Map of Science — an interactive dependency graph for the entirety of human scientific knowledge.
It’s simple: every scientific theory is a node, every derivation/dependency is an edge. You can trace a path from basic
How to improve the performance of qubits: Super-fast fluctuation detection achieved
Using commercially available technology and innovative methods, researchers at NBI have pushed the limits of how fast you can detect changes in the sensitive quantum states in the qubit. Their work allows researchers to follow rapid changes in qubit performance that were previously invisible. The study is published in the journal Physical Review X.
Ultrafast quantum chemistry engine could speed up the development of new medicines and materials
The powerful software can reduce the time needed to simulate reactions with large molecules from weeks to just minutes.
Quantum reservoir computing peaks at the edge of many-body chaos, study suggests
Reservoir computing is a promising machine learning-based approach for the analysis of data that changes over time, such as weather patterns, recorded speech or stock market trends. Classical reservoir computing techniques are known to perform best at the "edge of chaos," or in simpler terms, at a "sweet spot" in which the behavior of systems is neither entirely predictable (i.e., order) nor completely unpredictable (i.e., chaos).
Human and AI. How to Modernize Your Consciousness in 10 Minutes
For someone let this be simply a joke, and for someone this will become a serious life turning point. Simply answer several questions to yourself. Reading these questions, you must understand that you are not only trying to position yourself, but at the same time you also learn about the opinion of other people through the text.I repeat, here the main idea is not a questionnaire, this is intended as a means of personal psychological support in positioning oneself. For many questions the answer s

Full disclosure: I'm an engineer.<p>I think you'll find the framing to be intuitive, useful and scary. It allows for elegant explanations for normal and abnormal brain phenomena. Dreams, depression, flow states, hypnosis, deja vu, drugs and so on.
