Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

We think of it as rigid, smooth, and unidirectional – the arrow of time flies straight and true, and all we can do is go ...

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 ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...

World Quantum Day explained, why April 14 links to Planck's constant, and how Google's 2026 Doodle highlights qubits and quantum ...

Have you ever thought that light might hold a key to life's mysteries? One hundred years ago, Alexander Gurwitsch dared to propose that living cells emit faint ultraviolet light, invisible to the ...
