Quantum physics has quietly been rewriting the rulebook on matter, and the latest breakthroughs suggest that the so‑called ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

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 ...

The pioneer of quantum computing talks about how Albert Einstein would have reacted to his experiments, the hype around the ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Teleportation via the internet sounds like science fiction. Still, researchers have now demonstrated quantum teleportation ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In the deadly game Russian roulette, a player loads a gun with a single bullet, spins the cylinder to randomize the bullet’s position, and turns the potentially lethal weapon on their own self. But in ...
