Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

The fragility and laws of quantum physics generally make the characterization of quantum systems time‑consuming. Furthermore, ...

In 2024, a quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber ...

To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

Quantum timekeeping has reached a new threshold, with trapped-ion clocks now accurate to the 19th decimal place and a ...

For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

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 ...

The truth is that even the most optimistic vendor estimates for this would put very nascent stages of enterprise value toward ...

Physicists have coaxed particles of light into undergoing opposite transformations simultaneously, like a human turning into a werewolf as the werewolf turns into a human. In carefully engineered ...
