We study standard protocol 
for teleporting the one-qubit state with both the
transmission process of the two qubits constitute the quantum channel and the recovery
operations performed by Bob disturbed by the decohering environment. The results revealed
that Bob’s imperfect operations do not eliminate the possibility of nonclassical
teleportation fidelity provided he shares an ideal channel state with Alice, while the
transmission process is constrained by a critical time
t0, c longer than
which will result in failure of if the two qubits are corrupted by the decohering
environment. Moreover, we found that under the condition of the same decoherence
rate γ, the teleportation protocol is significantly more fragile when
it is executed under the influence of the noisy environment than those under the influence
of the dissipative and dephasing environments.
