The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Why is quantum mechanics important? We are used to seeing the world at the macroscopic level. Our eye does not perceive what is really there at its microscopic level, and (maybe) it is better that way ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

The theory of quantum mechanics has transformed daily life since being proposed a century ago, yet how it works remains a mystery—and physicists are deeply divided about what is actually going on, a ...

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving ...

While William Rowan Hamilton isn’t a household name like, say, Einstein or Hawking, he might have been. It turns out the ...

For decades, quantum computing has felt like something out of science fiction — abstract, theoretical, and always “10 years ...
