Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

According to a new theory, our universe developed from a “pre-inflationary multiverse” made of particles in quantum superposition.

The investigation into quantum mechanics and identity in physics explores the profound implications of particle indistinguishability and the emergence of distinct identities from fundamentally ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study ...

Chinese scientists have cracked a long-standing puzzle in quantum optics, creating a tiny device that spits out pairs of ...

Add Yahoo as a preferred source to see more of our stories on Google. Two Physical Review A papers outline how anyons could exist in one dimension, and how cold-atom experiments might spot them.

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

NVIDIA, the AI boom's $4 trillion chipmaker, is now betting on quantum computing—despite doubts about how soon the technology will pay off.
