Hello quantum world

“We have this device that is more complicated than you can simulate on a classical computer, but it’s not yet controllable to the precision that you could do the algorithms you know how to do.”

It doesn't sound like it's usable yet. It's just a serious computer now. Maybe it means that they consider it as a seriously potential machine but it have not acquired any usability in actuality yet.

To this day, I still don't understand if "spooky action at a distance" is a thing and if there is actually any sort of connection between entangled particles. People vehemently, dramatically claim one side or the other with no support...or I don't get it.

Was just reading this: https://en.wikipedia.org/wiki/CMB_cold_spot

And how it's "proof of a parallel universe that is quantum-entangled with ours." Don't understand any of it.

Someone on here explained quantum radar to me - that's about the only "quantum" thing that made sense to me.
