Quantum Entanglement Happens Faster Than We Ever Thought

Scientists have recently made amazing discoveries about how fast things happen at the tiniest scales in the universe. They've measured events that occur in attoseconds, which are incredibly brief moments of time. To give you an idea of how quick an attosecond is, it's one quintillionth of a second — that's 0.000000000000000001 seconds!

Using this ultra-precise timing, researchers found that quantum entanglement — a strange phenomenon where two particles become connected and instantly affect each other, no matter how far apart they are — actually takes about 1.8 attoseconds to happen.

Previously, many thought these quantum events were instantaneous, meaning they happened in no time at all. However, this new research from the Vienna University of Technology shows that even these lightning-fast processes have a measurable speed. This suggests that the speed of light is a fundamental limit, even for quantum events.

This discovery shows us that even the quickest events in the universe aren't truly instantaneous — they happen incredibly fast, but at a speed we can now measure and study. This opens up new possibilities for quantum computing and particle physics.
