A modification of the traditional installation for teleportation of the quantum state of a qubit is considered. On the transmitting side, the sequence of the CNOT gate and the Hadamard gate is reversed. The modified installation now makes it possible to teleport not just the unknown state of a qubit, but the state of entanglement of qubits. On the transmitter side, the installation puts two qubits into a state of entanglement, as a result of which two qubits on the receiver side also find themselves in a state of entanglement. The possibility of direct superluminal transmission of classical information using the CNOT gate is also shown.
