Does modifying the state of one entangled particle then destroy the link between them? If it does, then how can you continually communicate without distance being a factor as you'll have to resupply? I hope it doesn't or there is some work around or I simply am completely asking the wrong question.
- jomamaxx 10y agoYes, the observation destroys the entanglement. The communication does not really happen between the state that is 'teleported' - you still have to manually send the photons 6km or whatever. But - very crudely - you can pass information from one entangled particle to it's pair 6km away and observe the results. So, you still have to have a fiber or whatever. Also - because it's all probabilistic and you don't know for sure if it worked in any given instance, you still need another classical channel to communicate information about what was passed in the first place.
- sebringj 10y agoThank you for answering. I am still hopeful there will be another property found out about quantum behavior that will allow instant communication to be a reality.
