entanglement speed measured

[scruffy]

232 attoseconds, according to this paper.

Quantum entanglement speed is measured for the first time, and it's too fast to comprehend

Quantum entanglement is where two particles become interconnected and share a single state. But how and when do particles become entangled?

Which means it's finite.

That's about 1/5 of a femtosecond.

"Not instantaneous". We have lasers that can keep up.

The experiment involves zapping an atom with so much energy that it kicks out an electron, AND forces the remaining electron into a higher orbital. The two electrons then turn out to be entangled.

Since it apparently takes a finite amount of time to entangle two quantum states, it is reasonable to conjecture that it also takes a finite amount of time to collapse them.

Which begs the question of ultra-fast measurements.

I know someone extremely smart who believes that Universe ( or, the Now) changes/ pulses at over 22 trillion times a second .
I mean an amazingly smart guy .
But I have no idea how he arrives at that belief .
Ring any bells ?

I appreciate that it does not come from Quantum Theory although it might coincidentally sit nicely alongside Entanglement .
But that is just my idle speculation .

The concept that the universe is essentially turning on and off (obviously, at incredibly small intervals), is something I've heard proposed long ago. It was in the context of speculating that, if it does go "off", even though it seems a short time to us, "off" is "off", and we have no idea how long that might really be and what is going on while it happens.

In the party of Alabama where I grew up we learned all that in seventh grade science.

Sure you did.
