• Abstract: This work presents a two-way teleportation protocol for the transfer of an unknown two-qubit quantum state between two parties Alice and Bob, utilizing a six-qubit cluster state. This bidirectional exchange is achieved by performing Bell measurements on the qubit pairs of Alice and Bob, ensuring the successful teleportation of the quantum state for both parties. We demonstrate the proposed protocol by designing a teleportation circuit that incorporates the necessary quantum gates. The fidelity of the teleportation process is evaluated through simulations, confirming the accuracy and reliability of the proposed scheme. The protocol restores teleported states without requiring CNOT operations or auxiliary qubits, offering a significant advantage in resource efficiency(utilization). A comparative analysis of the intrinsic efficiency with previous approaches establishes that the proposed protocol brings forth an efficient approach for achieving two-way quantum teleportation.

  Quantum teleportation is a primitive protocol for exchanging quantum information in a quantum network. We propose a scheme wherein Bell-like states are being exchanged simultaneously in cyclic sequence. Based upon communication- and operation- complexity, we compare our protocol with other equivalent protocols and found that the intrinsic efficiency of our protocol is maximum pegging at 33.33%.
