Two Phase Communication Protocol of a Two Qubit States using Concatenated GHZ States

Abstract: In this paper we introduce a new communication (teleportation) protocol for transferring arbitrary two qubits by using concatenated three particle entangled states as quantum channels which are robust in noisy environments. Due to almost inevitable existence of noise, which can create devastation in the communication systems, such robust quantum channels become necessary. The protocol is a perfect teleportation protocol. An advantage of the process is that only one fourth of the measurement basis elements of the sender appear in the protocol.
