A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.

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

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the ...

Quantum technologies, computers or other devices that operate leveraging quantum mechanical effects, rely on the precise ...

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