If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ever ‘superposition’ — a quantum state in ...

Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...
