A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the ...

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 ...

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these ...

Scientists have created a new way to generate powerful quantum interactions, achieving the first-ever demonstration of ...

Diamond is extremely valuable to science and technology not for its sparkle but for its extreme hardness, high thermal ...

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, ...

How come our universe is full of disorder, when all elementary particles appear to follow strictly ordered laws of physics? And are there organizing principles behind disorder and apparent chaos?

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

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 idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of science is under construction that centres conscious experience – and might ...
