Abstract

Quantum teleportation with optimum quantum resources and hardware in a quantum network poses a pressing and demanding need. Here, we offer a protocol for asymmetric two-way controlled quantum teleportation via employing a sixteen-qubit entangled state as a resource in a quantum network consisting of five communicating participants Alice, Bob1, Bob2, Bob3and Eve. Our protocol is designed so that a sending party (Alice) transmit its three single information-qubits to three different parties Bob1, Bob2& Bob3, respectively and at the mean time, these three parties (Bob1, Bob2& Bob3) send their Bell-like information-qubits back to the sender (Alice) under the supervision of administrator (Eve) by invoking projective Bell State measurements, GHZ-state measurements and X-basis measurements and local unitary operations. Furthermore, we have analyzed intrinsic efficiency of the protocol and compare our scheme with other competitive protocols.

Simultaneous Multiparty Quantum Teleportation Supervised by a Controller

Nikhita Singh, Ravi Shankar Singh

Quantum network harbours a technology of multiparty transmission and computation of quantum information. We here design a quantum circuit comprising of Hadamard and controlled-Not gates for preparation of a cluster state of symmetric and antisymmetric Bell pairs involving seventeen qubits which is later on utilized as a quantum channel. This seventeen qubits quantum channel is employed to strategize a simultaneous multiparty (quattro directional) quantum teleportation protocol in which four senders (Alice, Bob, Charlie and David) transmit their arbitrary unknown two-qubit states to respective four receivers (Fancy1, Fancy2, Fancy3 and Fancy4) under the supervision of a controller Elle. After successful accomplishment of the protocol, we assess and compare our scheme with contemporary protocols based on quantum (classical) resource consumption, transmitted qubits, operation complexity and efficiency. We found that intrinsic efficiency of our protocol pegs at 21.65 percent.

Bidirectional Quantum Teleportation by Using Two GHZ-States as the Quantum Channel

Vikram Verma

Bidirectional quantum teleportation protocol enables two way quantum communication between two quantum nodes in a quantum communication network. In quantum network, the quantum nodes are linked to each other through a quantum channel. In this letter, by using the quantum channel composed of two three-qubit GHZ states, we propose an improved protocol for asymmetric bidirectional quantum teleportation which is based on local CNOT gate operations, Bell state measurements, GHZ-state measurements and unitary operations. Compared with previous protocols for bidirectional quantum teleportation, the proposed protocol requires less consumption of quantum and classical resources, possesses higher intrinsic efficiency and less operation complexity.

Asymmetric cyclic controlled quantum teleportation by using a quantum channel composed of six G states

Benchao Yang

In the existing research on cyclic teleportation protocols, it is generally discussed that the teleportation of single particle, two particle unknown quantum states with symmetrical structure or asymmetric special unknown quantum states (such as GHZ state) with three or four participants. In contrast, the scheme proposed in this paper has universality and stronger practicability. In this paper, we propose a novel scheme of asymmetric cyclic controlled teleportation. In our scheme, Alice can teleport an arbitrary single-qubit entangled state to Charlie, Charlie can teleport an arbitrary three-qubit entangled state to Bob and at the same time Bob can teleport an arbitrary two-qubit entangled state to Alice under the control of a controller David. It only needs Bell measurement and local unitary operation, and can realize three-party cyclic transmission with probability 1 by using a quantum channel composed of any six of the 16 G states.

Asymmetric bidirectional quantum teleportation via six-qubit partially entangled state

Jinwei Wang, Liping Huang

In this paper, an asymmetric bidirectional controlled quantum teleportation via a six-qubit partially entangled state is given, in which Alice wants to transmit a two-qubit entangled state to Bob and Bob wants to transmit a single-qubit state to Alice on the same time. Although the six-qubit state as quantum channel is partially entangled, the teleportation is implemented deterministically. Furthermore, only Bell-state measurements, single-qubit measurements and some unitary operations are needed in the scheme.

Symmetric-Cyclic Bidirectional Quantum Teleportation of Bell-like State via Entanglement-Swapping

Nikhita Singh, Ravi Shankar Singh

Quantum teleportation is a primitive foundational protocol for exchanging quantum information in a quantum network as well as infrastructural operational strategy in the measurement-based quantum computation. Designing an efficient scheme for quantum teleportation is a vibrant field of intensive research. We propose a scheme wherein Bell-like states are being exchanged simultaneously in cyclic sequence, i.e., symmetric-cyclic bi-directional quantum teleportation, amongst three communicating parties forming a quantum network, Alice, Bob and Charlie via entanglement-swapping with the aid of a cluster of three maximally entangled GHZ-states as the quantum channel. Moreover, based upon communication- and operation- complexity, we compare our protocol with other equivalent protocols and found that the intrinsic efficiency of our protocol is maximum pegging at 33.33%.

Enhanced Two-Way Teleportation of Entangled States with Six-Qubit Cluster State

This work presents a two-way teleportation protocol for the transfer of an unknown two-qubit quantum state between two parties Alice and Bob, utilizing a six-qubit cluster state. This bidirectional exchange is achieved by performing Bell measurements on the qubit pairs of Alice and Bob, ensuring the successful teleportation of the quantum state for both parties. We demonstrate the proposed protocol by designing a teleportation circuit that incorporates the necessary quantum gates. The fidelity of the teleportation process is evaluated through simulations, confirming the accuracy and reliability of the proposed scheme. The protocol restores teleported states without requiring CNOT operations or auxiliary qubits, offering a significant advantage in resource efficiency(utilization). A comparative analysis of the intrinsic efficiency with previous approaches establishes that the proposed protocol brings forth an efficient approach for achieving two-way quantum teleportation.
