Asymmetric tridirectional quantum teleportation using seven-qubit cluster states

Abstract

This paper proposes an asymmetric tridirectional quantum teleportation (TQT) protocol that uses a seven-qubit cluster states as the quantum channels of each party. In this scheme, any one of the three participants can send their arbitrarily entangled states to the other two concurrently. The tridirectional functionality shows that all three users can act as sender and receiver simultaneously. Based on the mathematical modeling of the scheme, the quantum circuit and the appropriate quantum channel is proposed. For examination and implementation, the proposed scheme and circuit were simulated and validated using IBM quantum experience platform, QASM_simulator and Qiskit library.
