Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, ...

An international team of physicists has uncovered a subtle but important twist in how “memory” works in quantum systems.

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

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

For more than 40 years, scientists have known that the quantum Hall effect impacts electrons in strong magnetic fields, but it turns out light also follows the fundamental phenomenon.

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 ...

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 ...

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

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 ...

Physicists at Boston University have achieved what amounts to a long-sought benchmark in quantum measurement: detecting the ...
