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, ...

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

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

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

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

Add Yahoo as a preferred source to see more of our stories on Google. Researchers at Brown University in the US have observed fractional excitons, a new class of quantum materials in a global first.

What makes something quantum? This question has kept a small but dedicated fraction of the world's population—most of them quantum physicists—up at night for decades. At very small scales, we know the ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

What makes something quantum? This question has kept a small but dedicated fraction of the world’s population – most of them quantum physicists – up at night for decades. At very small scales, we know ...

Physicists have forced light to behave like electrons trapped in a magnetic field, reproducing the quantum Hall effect with photons for the first time. The experiment, carried out on an optical fiber ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
