A quantum internet is only as useful as its reach, and in a first, researchers created more than a million qubit pairs across ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

About 13.8 billion years ago, the origin of the universe began with the Big Bang. Scientists say all space, time, matter, and ...

In classical physics, memory is defined in a straightforward way. If a system’s future behavior depends only on its current condition, it is considered memoryless. If earlier states continue to ...

When Richard Feynman first conceived of quantum computers in the 1980s, he believed they should primarily investigate quantum phenomena. So that’s what a group of chemists did: they used quantum ...

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To ...

What was your favorite toy growing up? This paradox claims that memory—and every other one—is just a random fluctuation.

Maria Goeppert Mayer is remembered as one of the most important physicists of the twentieth century. She was born in Germany ...

The original story “ Physicists build a quantum Newton’s cradle where energy flows without resistance ” is published in The ...

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a black hole.
