In this contribution, we investigate bidirectional quantum teleportation of single-qubit state, for the case in which qubits from the quantum channel of teleportation are distributed by typical correlated noisy channels such as bit-flip, phase-flip, depolarizing, and amplitude damping channels. Expressions of the negativity of the partially transposed density operator, fidelities of teleportation, and quantum Fisher information are evaluated, we found that all these quantities depend on factor noise and the correlation strength of the noisy channel. It is shown that the effect of the noise on entanglement, averaged fidelities of teleportation, and on quantum Fisher information could be noticeably reduced due to the existence of the noise channel correlations.
