We proposed an N-qubit GHZ-like state quantum teleportation protocol using a two-qubit entangled quantum channel state assisted with only one classical bit. In this protocol, we use CNOT gates and a reset procedure, assuming the sender has many copies of the state that will be teleported. The CNOT gates can reduce the number of N-qubit to only one qubit, while the reset procedure may reduce the number of classical bits required to only one classical bit. Lastly, we show that the teleportation success probability depends on the state of the N-qubit state's coefficients and is generally more than one-half.
