Abstract
This article presents a new bidirectional teleportation protocol for an arbitrary number of qubits which employs \(2n\) entangled Bell-states (4n-qubits) as the quantum channel. Alice intends to transmit an arbitrary unknown qubit state to Bob in the proposed scheme and vice versa. For establishing the protocol, \(2n\) Bell-states are specified in the channel for both parties to load their qubits. Using Bell-states, input states are teleported over the channel using Bell-basis measurements and applying a proper unitary operator. Thus, the communication purpose is more privileged than recently presented protocols since the proposed protocol is more straightforward and uses the minimum resources. Furthermore, the circuit of the scheme is implemented in the IBM Quantum experience platform using qasm_simulator and Qiskit library, and the outcomes verify the validation of the protocol. Moreover, the amplitude damping noise effect is analyzed and simulated using Qiskit.
