Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

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 ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Scientists test Einstein’s quantum challenge with one atom, directly measuring when photon paths erase interference stripes.

Appearance is one thing, but reality is another. The world does not appear to be a hologram, but maybe it is. Thus begins physicist Leonard Susskind in opening a doorway between science and religion ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Viruses exist at the boundary between living and non-living matter, while skin is a living interface between physics and biology, making them perfect—but until now overlooked—arenas for testing the ...

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 ...

Some researchers believe consciousness is a byproduct of the constantly firing web of neurons in our heads. However, others believe something more theoretical must be involved to explain our complex ...
