“spooky action at a distance”<p>It seems that everything I read states that this isn't actually a thing: No information can be transferred, nothing is changed at a distance. Is that wrong? This is so confusing.<p>This is the speed of what exactly?<p>There is the old related link here: <a href="https://www.sciencemag.org/news/2017/06/china-s-quantum-satellite-achieves-spooky-action-record-distance" rel="nofollow">https://www.sciencemag.org/news/2017/06/china-s-quantum-sate...</a><p>Are the satellites basically signing the message kind of like quantum radar?
