“Quantum entanglement speed. It’s in excess of 10000 times the speed of light.”
- madeuptempacct 8y ago“spooky action at a distance” 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. This is the speed of what exactly? There is the old related link here: https://www.sciencemag.org/news/2017/06/china-s-quantum-satellite-achieves-spooky-action-record-distance https://www.sciencemag.org/news/2017/06/china-s-quantum-sate... Are the satellites basically signing the message kind of like quantum radar?
