This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

When scientists repeatedly drove a strongly interacting quantum system with laser “kicks,” they expected it to heat up and ...

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 ...

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.

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

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 ...

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 ...

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 ...

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 ...
