“…In absence of the controller, a BCST scheme can be reduced to a BST scheme. In the light of our present results, some of the recent schemes of CT using 4-qubit cluster state [21] and QIS using 4 and 5-qubit cluster state [11,23]; BST using 3-qubit GHZ state [18]; and 6-qubit cluster state [20], can also be performed with reduced amount of quantum resources (entangled states involving lesser number of qubits).…”

“…Another kind of optimization has been attempted in some recent works. Specifically, efforts have been made to form teleportation channel (having lesser number of entangled qubits) suitable for the teleportation of specific types of unknown quantum states [11,[17][18][19][20][21][22][23][24][25][26][27][28][29]. For example, in [17], the 3-qubit and the 4-qubit unknown quantum states have been teleported using 4 and 5-qubit cluster states, respectively.…”

An explicit scheme (quantum circuit) is designed for the teleportation of an n-qubit quantum state. It is established that the proposed scheme requires an optimal amount of quantum resources, whereas larger amount of quantum resources has been used in a large number of recently reported teleportation schemes for the quantum states which can be viewed as special cases of the general n-qubit state considered here. A trade off between our knowledge about the quantum state to be teleported and the amount of quantum resources required for the same is observed. A proof of principle experimental realization of the proposed scheme (for a 2-qubit state) is also performed using 5-qubit superconductivity-based IBM quantum computer. Experimental results show that the state has been teleported with high fidelity. Relevance of the proposed teleportation scheme has also been discussed in the context of controlled, bidirectional, and bidirectional-controlled state teleportation.

“…Since bidirectional quantum teleportation protocol was first proposed in 2013, many bidirectional quantum teleportation protocols have been proposed. However, in these presented protocols, quantum information bits transferred by two communicating parties are generally two single-qubit states [16], [17], [21]- [24] a single-qubit state and a two-qubit state [20], [25], [26], two two-qubit states [27], [28], the aim of this paper is to increase the number of quantum information bits transmitted by communicating parties. So, it is an innovational theory to use a three-qubit entangled state and a single-qubit state as quantum information bits transmitted.…”

Quantum teleportation is considered as the most basic process of quantum communication. It is undoubtedly beneficial for the realization of quantum teleportation while transmitting the maximum number of quantum bits with the minimum number of quantum channel resources. An improved bidirectional quantum teleportation protocol based on a quantum channel of six-qubit cluster state is proposed. In this paper, the user Alice can transmit an unknown three-qubit entangled state to the user Bob, and at the same time, the user Bob can transmit an arbitrary single-qubit state to the user Alice by utilizing GHz-state measurement, bell-state measurement, single-qubit Von Neumann measurement, and unitary operations. Compared with other schemes in quantum resource consumption, necessary operation complexity including operation difficulty and intensity, classical resource consumption, quantum information bits transmitted, and intrinsic efficiency, our scheme has the remarkable advantages in transmitting more quantum information and possesses higher intrinsic efficiency.

“…A direct way for bidirectional quantum teleportation is to use two quantum teleportations with two Bell states: from Alice to Bob and vice versa. A number of alternative approaches to bidirectional quantum teleportation based on n-qubit entangled states with n > 4 [41][42][43][44] and GHZ states [45] has been suggested.…”

Bidirectional imperfect quantum teleportation with a single Bell state

We present a bidirectional modification of the standard one-qubit teleportation protocol, where both Alice and Bob transfer noisy versions of their qubit states to each other by using single Bell state and auxiliary (trigger) qubits. Three schemes are considered: the first where the actions of parties are governed by two independent quantum random triggers, the second with single random trigger, and the third as a mixture of the first two. We calculate the fidelities of teleportation for all schemes and find a condition on correlation between trigger qubits in the mixed scheme which allows us to overcome the classical fidelity boundary of 2/3. We apply the Choi-Jamiolkowski isomorphism to the quantum channels obtained in order to investigate an interplay between their ability to transfer the information, entanglement-breaking property, and auxiliary classical communication needed to form correlations between trigger qubits. The suggested scheme for bidirectional teleportation can be realized by using current experimental tools.Comment: 8 pages, 4 figures; published versio
