Actually that isn't the issue, entanglement can already do that.

Oh good, quantum stuff gets even more weird

(paraphrasing Sean Carroll from memory here)

As I understand it, even though the action is instantaneous over distance due to entanglement, because neither party can communicate this to the other, information isn’t traveling faster than the speed of light.

Then how did he explain it as one of the particles can be many light years away and know the Planck time moment it's mated pair changes.?

I don’t know, I think he might say something like if you look at the equations then you can see that distance is not a relevant factor.

That's why Einstein hated the idea so much, it broke one of his fundamental laws.
