In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they can occupy several possible states at once, a phenomenon known as ...

Quantum technology has promising potential to revolutionize how large and complex amounts of information are processed. While ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Scientists measured negative time in a quantum physics experiment using photons and rubidium atoms, calling it an unusual behavior.

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal ...

This spring, physics has delivered a trifecta of breakthroughs that are reshaping our grasp of the universe: a landmark fusion agreement for stellarators, a new form of quantum matter called a time ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

The concept of entanglement links far-flung particles. That relationship can prove that someone is in the location they claim ...
