Quantum entanglement cannot transmit information. Full stop. Let alone FTL.

When you measure an entangled particle that tells you, the observer, the corresponding characteristic of the other particle in the pair, but it will tell no one who has access to the other particle anything at all about what you wanted to say.

This is like transmitting information from you to you about a faraway thing (instantaneously! "FTL", but read on), but it's not useful because what you want to transmit information from you to someone else far away rather than from you to you.
