This is how quantum teleportation works.
Alice and Bob have entangled qubits A and B, and also Alice has a qubit C with some state that she wants to send to Bob , and Bob has some other Qubit D. To do this, Alice does some operations between qubits A and C, which includes a measurement. Alice then sends the classical information which is the result of the measurement to Bob. Bob then does some operations with the qubits B and D, where the operations he does are chosen based on the classical information signal he received from Alice. Iirc these observations include making a measurement. As a result, the qubit D is now in the state that the qubit C was in originally. (Alice no longer has access to the state that C was in.) So, in a sense, the state teleported from C to D, using the combination of the entangled A and B, along with sending some classical information. (The classical information sent is random, and to anyone snooping on the message sent, gives them no useful information, because they don’t have Bob’s qubit B to use it with.)
These simply do not do what you think they do. Information cannot, under any currently theorized model of physics, be transmitted faster than light.
