A rewarding book that offers a cogent look at the science’s history and the second quantum revolution that’s under way ...

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

Is the electron a wave or a particle? Are the orbits of electrons in atoms similar to planetary orbits? What is the nature of light? Such were the questions that physicists were struggling with in the ...

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

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 ...

A new study in Nature Physics has turned an old problem on its head by reporting a way to use the noisy interactions between ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

On the morning of June 28, 1914, a Bosnian Serb student named Gavrilo Princip stood outside Moritz Schiller’s delicatessen near the Latin Bridge in Sarajevo. Sometime after 10:45 A.M., a motorcade ...

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 ...
