“…By drawing the measurement-less quantum circuit representation of the related schemes presented in [15][16] [17] and [18](where the teleported state is |Ψ C )we have evaluated the quantum cost, gate count and classical bits used in the schemes and are tabulated along with the results in our proposed schemes in table:5. In [15], a five qubit entanglement channel and five-particle joint measurement is used, where as in [16] three sets of four-qubit cluster states has been used to complete the same quantum task. The quantum cost of these schemes shows that they are not as efficient as the other schemes.…”

“…Liu and Zhou [15] worked out a scheme for teleportation of a specific form of tripartite state (with four unknown coefficients) using five qubit cluster state. Chaudhary and Dhara [16] showed that the tripartite states of the form similar to the one used in [15] can be teleported using three sets of four-qubit cluster states. Later, Wei et.al.…”

“…These three-particle states are related to each other by unitary transformations σ x2 |Ψ A 123 = |Ψ C 123 , σ x2 |Ψ B 123 = |Ψ D 123 , CNOT(3, 2) |Ψ A 123 = |Ψ B 123 and CNOT(3, 2) |Ψ C 123 = |Ψ D 123 , where, {I, σ x , σ y , σ z } represents Pauli matrices. The teleportation of the tripartite state |Ψ C 123 has been discussed in [15], [16], [17] and [18]. In this section, we investigate the possibility of teleporting all these special class of arbitrary tripartite states given in equation:2, using four-qubit cluster state as entanglement channel.…”

In this paper we propose two schemes for teleportation of a sub-class of tripartite states, the first one with the four-qubit cluster state and the second one with two Bell pairs as entanglement channels. A four-qubit joint measurement in the first case and two Bell measurements in the second are performed by the sender. Appropriate unitary operations on the qubits at the receiver's end along with an ancilla qubit result in the perfect teleportation of the tripartite state. Analysis of the quantum circuits employed in these schemes reveal that in our technique the desired quantum tasks are achieved with lesser quantum cost, gate count and classical communication bits compared with other similar schemes.

Abstract. Recently Liu et al.(Int. J. Theor. Phys. 53:4079, 2014) had shown that a special form of three-qubit entangled state can be teleported by using a fivequbit cluster state. However, we demonstrate that five-qubit cluster state and five-qubit von-Neumann projective measurements are not necessary to complete the protocol. The special three-qubit state can be teleported via a four-qubit entangled state, by introducing one ancillary qubit and one controlled-not operation. Physical realization of the proposed four-qubit entangled state and the generalization to teleport the multi-qubit state is also presented.

It is crucial to design quantum circuits as small as possible and as shallow as possible for quantum information processing tasks. Quantum circuits are designed with simplified gate‐count, cost, and depth for implementing quantum teleportation among various entangled channels. Here, the gate‐count/cost/depth of the Greenberger‐Horne‐Zeilinger‐based quantum teleportation is reduced from 10/6/8 to 9/4/6, the two‐qubit‐cluster‐based quantum teleportation is reduced from 9/4/5 to 6/3/5, the three‐qubit‐cluster‐based quantum teleportation is reduced from 12/6/7 to 8/4/5, the Brown‐based quantum teleportation is reduced from 25/15/17 to 18/8/7, the Borras‐based quantum teleportation is reduced from 36/25/20 to 15/8/11, and the entanglement‐swapping‐based quantum teleportation is reduced from 13/8/8 to 10/5/5. Note that, no feed‐forward recover operation is required in the simplified schemes. Moreover, the experimentally demonstrations on IBM quantum computer indicate that the simplified and compressed schemes can be realized with good fidelity.
