“…The application of the teleportation process has been recognized to be quite wide in quantum information theory ranging from satellite-based communication [23][24][25] in the large to teleportation over the chip in the small scales [26][27][28][29][30]. Since the 3-qubit state we intend to teleport has special characteristics as mentioned in [21] (2m + 6) + 3 3 < 3 9…”

In this paper we describe two different probabilistic teleportation protocols for teleporting the same unknown 3-qubit state from the sender Alice to the receiver Bob. The speciality of the state is that it remains a 2-qubit entangled state after any of the three involved qubits is eliminated by partial trace operation. One of the protocols utilizes a two and a three-qubit separate channels while in the other protocol, a five-qubit channel is utilized. One of the channels in the first protocol is a non-maximally entangled Bell state while the 5-qubit channel used in the case of the second protocol is non-maximally entangled. Both the teleportation schemes are probabilistic with the feature that in the case of failure of the teleportation, the state to be teleported is not lost to the sender. So the process can be repeated after failure till success is achieved. Moreover, one of the channels is recovered in the failure case. Both protocols are resumable in the above sense. The above is the speciality of the present work. We analyze the efficiency of our protocol which shows that the present two protocols are better performing than some existing ones.

“…The symbols used are conventional and the steps executed herein are self-explanatory. which has been discussed in works like [28][29][30]. In such situations, the use of ancilla qubits accessible to both the sender and receiver can reduce the number of qubits which would have been otherwise involved in the quantum channel.…”

“…Since multi-qubit entangled states are difficult to produce, in any possible reduction in the number of qubits in the entangled channel is a welcome feature in the communication process. Tan and Han [26] first presented a short-distance teleportation protocol of an arbitrary two-qubit state. This approach utilizes a Bell state as the quantum channel and an auxiliary particle in the ground state |0⟩.…”

Teleportation across short distances has become relevant in view of some recent developments in quantum technology. The advantage here is that certain auxiliary qubits can be accessed and utilized by both the sender and the receiver. Such act reduces the requirement of the number of qubits in the entangled quantum channel which would have been otherwise necessary. In this paper we present a short-distance teleportation protocol by which an arbitrary three-qubit state can be transferred with the help of auxiliary qubits and a maximally entangled Bell-State. In the second part of the paper we introduce a probabilistic short-distance protocol for the same arbitrary three-qubit state by using a non-maximally entangled Bell-state. The success probability of the protocol is calculated and its relation with the first protocol is discussed. We presented a circuit diagram for the first protocol and execute it in the IBM-QE platform.
