Hello quantum world
- elorant 8y agoIn every article about quantum computers I have a hard time distinguishing what's reality and what's pure fiction, or simply put journalists who don't understand what they're writing about.
- madeuptempacct 8y agoTo 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 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.
- speakeron 8y agoThe short answer is that statements like "spooky action at a distance" are an attempt to shoehorn quantum mechanics into a classical framework. It doesn't have any meaning in that sense. The long answer is here: https://www.youtube.com/watch?v=0Eeuqh9QfNI https://www.youtube.com/watch?v=0Eeuqh9QfNI
- KenanSulayman 8y ago"Serious quantum computers are finally here." What does "serious" mean in this context? Do we actually have usable, serious quantum computers?
- cjohansson 8y ago“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.
