Perfect randomness sounds simple, until you try to make it. A die can be polished, balanced and rolled thousands of times.

Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational ...

Manuel Endres, professor of physics at Caltech, specializes in finely controlling single atoms using devices known as optical tweezers. He and his colleagues use the tweezers, made of laser light, to ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

A new debate in quantum physics is shaking the foundations of modern science. Tim Palmerargues that nature may not follow ...

Researchers have designed a quantum version of a pendulum clock. It could shed light on timekeeping in the quantum realm ...

Quantum computing still stumbles on fragility, where tiny disturbances can wreck calculations. ETH Zurich researchers built a ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

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 ...
