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 ...

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

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 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 ...

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 ...

Main ideas of the article are further expanded on in this online lecture by the author. Faced with this problem, I realized that the ultraviolet radiation he described might be explained using quantum ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the earliest moments of the universe. While interesting, and potentially even ...

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

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