SETI public: Quantum Entanglement article

Unfortunately, I accidentally deleted the quantum entanglement article,
but it repeated a common misconception.

If you read the states at one end only, you end up with total gibberish.
  You can only transmit real information if you also read the states at
the other end and transmit them using light speed limited mechanisms.

 From an engineering point of view, there is also the problem of
preventing the particles losing their state in transit.

What quantum entanglement enables you to do is to reproduce quantum
states at the sending end when normal interactions with what is being
constructed at the receiving end would leave its state unknown.

There are some interesting questions about the nature of simultaneity,
that I haven't seen answered, but there is no suggestion that real
information can be transmitted faster than light.

that is no longer good advice, as archive address hiding may not work.
