It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

Quantum physics is a very diverse field: it describes particle collisions shortly after the Big Bang as well as electrons in solid materials or atoms far out in space. But not all quantum objects are ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

It took 125 years, but in 2025 a team of mathematicians discovered the solution to a long-puzzling problem about the ...

In the strange, often unintuitive world of quantum physics, one mystery has stood out for decades: Can quantum entanglement be manipulated in a reversible way, like energy in a perfect heat engine?

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...

The proposed model-checking approach can be used for the specification and verification of quantum circuits with their desired properties. Ishikawa, Japan-- Quantum computing is a rapidly growing ...
