At first when I heard about entanglement, I thought "Neat, so we can make a manipulation on our quantum computer here in such a way that can be interpreted as a binary output somewhere else, and have secure, instant communication of information across vast distance."
Then I read an article about the effect of quantum mechanics / computing on security and it was explained that we cannot manipulate the communicated information, we can just get the same random numbers from each end securely, which is still useful. So then my thinking was "Ok, so no messages, but very secure crypto key exchanges, that's still cool.."
And now I watch this video which at the time stamp linked suggested that we can manipulate one end and have that manipulation communicated at the other end.
So will I one day be able to send "Hello world" through a near zero latency, perfectly secure entangled particle pair, or will I not?
