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, ...

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 ...

For decades, time moved in one direction, now a growing number of quantum experiments are raising the unsettling possibility that the order of events may not be as fixed as humans once believed. For ...

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 produced experimental evidence that anyons, exotic quasiparticles long thought to exist only in two-dimensional systems, can emerge in strictly one-dimensional quantum platforms. The ...

Numerical simulation of gravitational waves within matter in a spin-nematic state. As these vortices spiral together and merge, they create waves that are mathematically identical to gravitational ...

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 ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science. Reading time 6 minutes The use of the word “quantum” has become ...

Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even ...

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 ...
