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

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 ...

Science in everyday conversation can feel distant— something conducted behind closed laboratory doors, far from big screens.

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

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it’s more difficult ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

Plausible science fiction occupies a space between imagination and inquiry. It does not promise answers so much as ...

Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, ...
