There is one very important caveat: quantum teleportation is really based on quantum entanglement. But,quantum teleportation is a change of condition of particles, not the transfer of information. You can create a system in which a state change will mean any symbol, for example 0 and 1 (as in the bit system). But to make work such system and be able to decipher the data, you need to compare the status of the sender and recipient. i.e. you need to pass additional information about the initial and nal states particles, which are connected by quantum entanglement. This additional information is transmitted by classical communication channels and the speed of its transfer can not exceed the speed of light. -a vicious circle.

And you can't do it without decoding and additional information and use only state of the particles, because as I wrote in the article - the wave function doesn't allow this.
