New discoveries demystify the bizarre force that binds atomic nuclei together

Researchers are racing to create codes so complex that even quantum computers can’t break them

Electrons swarm in a soup of quantum entanglement in a new class of materials called strange metals

In 1949 physicist Chien-Shiung Wu devised an experiment that documented evidence of entanglement. Her findings have been hidden in plain sight for more than 70 years

Experiments that imitate solid materials with light waves reveal the quantum basis of exotic physical effects

To understand why the universe is made of matter and not antimatter, physicists are looking for a tiny signal in the electron

Outcomes in quantum mechanics depend on observations. But must the observer be human?

A freak particle physics process could wipe out all galaxies and life—but it’s wildly unlikely

The Archimedes experiment will weigh the void of empty space to help solve a big cosmic puzzle

Proposed experiments will search for signs that spacetime is quantum and can exist in a superposition of multiple shapes at once
