An asymmetric bidirectional quantum controlled teleportation via a seven-qubit Werner-like mixed state is proposed. In the process of teleportation preparation, it is hypothesized that three imperfections could appear, namely (i) imperfection of the entangler device that may result in a non-maximal entanglement of the channel, (ii) local noises are introduced during the channel preparation process, and (iii) global noises occur during the channel state distribution to the corresponding parties. The local and global noises are selected as depolarizing noise with certain probability of transforming any entangled state into a maximally mixed state, resulting in a seven-qubit Werner-like mixed state. The teleportation fidelity with the presence of the imperfections is evaluated. It is shown that the teleportation is more robust under the presence of global noise compared to local noise.
