ever since the Chinese published that they can now use entanglent to transmit information faster than light. following it up with that quantum comms satelite recently im not sure what to think anymore.
surely a better answer is "we dont actually know anymore"

- lawpoop 10y agoYour summation is not true; all they've claimed to have done is create a quantum encryption link, which means that if someone tries to eavesdrop on it, it will garble the message for both recipients. There is no FTL communication.
- mSparks 10y agothats isnt how the project was billed. the first part of the project is quantum encryption. the second is ftl communication https://www.rt.com/news/328988-china-quantum-info-teleport/ https://www.rt.com/news/328988-china-quantum-info-teleport/ The satellite’s first mission would involve establishing a cryptographic communication line between Beijing and Vienna by creating “[the encoding and sharing of a secret cryptographic key using the quantum properties of photons] between a ground station in Beijing and the satellite, and between the satellite and Vienna.” Scientists then plan to conduct satellite entangled photon quantum teleportation between stations located in the Chinese cities of Delingha and Lijiang or Nanshan, which are separated by more than 1,200 kilometers. ____ following the ftl publications in 2013 Spooky!
