New digital state of matter could help build stable quantum computers

Scientists have taken another major step toward creating stable quantum computers. Using a specialized quantum computer chip (an essential component of a quantum computer) as a kind of tiny laboratory, a team led by Pan Jianwei at the University of Science and Technology of China has created and studied a rare and complex type of matter called higher-order nonequilibrium topological phases.

This digital matter (not conventional physical material) is unique because its key behaviors are super-stable and located only at its corners. But this stability is only maintained when the material is constantly bombarded with energy pulses.

The work is a big deal because it shows that quantum computers can be used as reliable simulators to discover and test new stable forms of matter. This will be necessary if scientists are to create quantum computers that never break down (or are at least highly reliable), because super-stable corner behaviors are the kind of error-proof properties needed to build trustworthy quantum hardware.

Natural language found more complex than it strictly needs to be—and for good reason

Human languages are complex phenomena. Around 7,000 languages are spoken worldwide, some with only a handful of remaining speakers, while others, such as Chinese, English, Spanish and Hindi, are spoken by billions. Despite their profound differences, they all share a common function: they convey information by combining individual words into phrases—groups of related words—which are then assembled into sentences. Each of these units has its own meaning, which in combination ultimately form a comprehensible whole.

“This is actually a very complex structure. Since the natural world tends toward maximizing efficiency and conserving resources, it’s perfectly reasonable to ask why the brain encodes linguistic information in such an apparently complicated way instead of digitally, like a computer,” explains Michael Hahn.

Hahn, Professor of Computational Linguistics at Saarland University, has been examining this question together with his colleague Richard Futrell from the University of California, Irvine. The paper is published in the journal Nature Human Behaviour.

Dynamic duo of bacteria could change Mars dust into versatile building material for first human colonists

Since humanity’s first steps on the moon, the aspiration to extend human civilization beyond Earth has been a central objective of international space agencies, targeting long-term extraterrestrial habitation. Among the celestial bodies within reach, Mars is considered our next home.

The red planet, with its stark landscapes and tantalizing similarities to Earth, beckons as the frontier of human exploration and settlement. But establishing a permanent foothold on Mars remains one of humanity’s boldest dreams and the most formidable scientific and engineering challenge.

The red planet, once draped in a thick atmosphere, has undergone dramatic transformation over billions of years. Its protective blanket vanished, leaving behind an environment nearly unrecognizable to terrestrial life.

Physicists create ‘quantum wire’ where mass and energy flow without friction or loss

In physical systems, transport takes many forms, such as electric current through a wire, heat through metal, or even water through a pipe. Each of these flows can be described by how easily the underlying quantity—charge, energy, or mass—moves through a material.

Normally, collisions and friction lead to resistance causing these flows to slow down or fade away. But in a new experiment at TU Wien, scientists have observed a system where that doesn’t happen at all.

By confining thousands of rubidium atoms to move along a single line using magnetic and optical fields, they created an ultracold quantum gas in which energy and mass move with perfect efficiency. The results, now published in the journal Science, show that even after countless collisions, the flow remains stable and undiminished, thus revealing a kind of transport that defies the rules of ordinary matter.

Google deletes X post after getting caught using a ‘stolen’ AI recipe infographic

Google is facing backlash on X after a viral post for its NotebookLM appeared to use a food blogger’s work without credit.

Recently, Google launched Nano Banana Pro, its most powerful image model to date.

The model is likely trained on millions of websites and videos, which explains why it’s one of the best tools for generating realistic images.
