Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Scientists have achieved a historic first using lasers to study electron behaviour, revealing new insights into how light ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

(Nanowerk News) Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Researchers have succeeded in measuring how energy dissipates in quantum dots by quantifying the entropy they produce. The work, by a team at Stanford University in the US, could help in the ...

Australia’s national science agency, CSIRO, has built a proof-of-concept quantum battery that completed a full charge, store, and discharge cycle at room temperature, with experimental results showing ...

Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge ...

At temperatures approaching absolute zero, most magnetic materials settle into tidy patterns. Their tiny magnetic moments, or ...
