String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

For a century, quantum theory has passed every experimental test, but physicists can’t agree on how to use it to paint a ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

When a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call ...

Scientists uncovered universal laws of entanglement in any dimension. The results strengthen links between particle physics, quantum theory, and gravity. A group of theoretical physicists has shown th ...

A survey of more than 1,000 physicists finds deep disagreements in what quantum theories mean in the real world ...

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

A new study shows quantum entanglement follows universal rules across dimensions using thermal effective theory.

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, connects quantum ...

Quantum Computation and Quantum Information by Nielsen and Chuang is the foundational text, covering algorithms, cryptography, and computational complexity. Qua ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...
