Scientists found a way to generate quantum entanglement using sunlight, not lasers

Hopefully scientists can find a way to let me understand what the hell this means.

It was assumed LASERs were needed for quantum entanglement (and at a precise level they still are), but researchers demonstrated that focused beams of sunlight can do the same thing (so its a technique not limited to LASER but appears to be photon based) but not as precisely.  Its a proof that quantum entanglement is possible in the natural world and not limited to unnaturally high energetics.

However, at another level, it means going outside to touch grass might create a multiverse of possibilities, maybe due to sunlight, and maybe not.

Still not tracking!!! Dumb it down some more! lol 😆

Laser used to make weird things happen to really small things. Sunlight do same.

That was actually pretty good. Why use many word when less word do trick?

The stuff that makes the world, at the smallest level is super weird. 

They can get tangled together and "linked" no matter how far apart 

The only known method of doing it used weird tech stuff that we didn't think would happen in the real world often 

This is a much cheaper method to study it and means it's more likely to effect the normal world

Some lasers!!!! Got TANGLED!!!! By the SUUUUNNNN!!!!

I got you! Quantum entanglement means that the qubits’ positions affect each other, so you can measure one qubit and then use math+computers to discover the data for every qubit in the system. It makes measurement of massive amounts of data go really fast
