Multi-Hop Quantum Communication Based on Greenberger-Horne-Zeilinger States and Teleportation

Na Chen, Shuangshuang Shuai, Bin Yan +2 more

Quantum teleportation faithfully transfers the quantum state of a physical system, instead of the system itself, which underlies the proposal of global quantum communication network. In this paper, we propose a faithful multi-hop quantum communication scheme. In a quantum network, different types of Greenberger-Horne-Zeilinger (GHZ) states are previously shared on quantum links. To implement qubits transmission, the sender and intermediate nodes perform quantum measurements in parallel, and then send their measurement results and the types of previously shared GHZ states to the receiver independently. A general formula is deduced for the receiver, who chooses an appropriate unitary operation to perform on the local particle, the original qubit can be retrieved. Our scheme shows advantages in quantum communication delay.Quantum teleportation faithfully transfers the quantum state of a physical system, instead of the system itself, which underlies the proposal of global quantum communication network.

Complete polarized photons Bell-states and Greenberger–Horne–Zeilinger-states analysis assisted by atoms

Yan Xia, Yi‐Hao Kang, Pei-Min Lu

We propose an efficient protocol for complete polarized photons Bell-states and Greenberger–Horne–Zeilinger (GHZ)-states analysis assisted by atoms. With the help of assistant atoms and some simple liner optical elements, the analysis of both polarization Bell states and GHZ states can be performed completely. In our protocol, the assistant atoms are trapped in cavity quantum electronic dynamics (QED), which is feasible with current experimental technology. Moreover, the polarized photons entangled states will not be destroyed in our protocol. Therefore, our scheme might contribute to the quantum communication, quantum computation, and some other fields in quantum information processing.We propose an efficient protocol for complete polarized photons Bell-states and Greenberger–Horne–Zeilinger (GHZ)-states analysis assisted by atoms.

Secure and Efficient n-Qubit Entangled State Teleportation Using Partially Entangled GHZ Channels and Optimal POVM

Animesh Banik, Md. Shihab Khan, Rafid Masrur Khan +2 more

We introduce an efficient and versatile quantum teleportation protocol for specific types of n-qubit entangled states. By employing a partially entangled Greenberger-Horne-Zeilinger (GHZ) state as the quantum channel and an optimal Positive Operator-Valued Measure (POVM) based on an improved reciprocal state formulation, we achieve unambiguous state discrimination. The scheme has been generalized to support various entangled state configurations and demonstrates a notable reduction in classical communication costs for these states compared to standard Bell-basis teleportation. Its capacity for integration with conventional protocols is pivotal, enhancing quantum hop-by-hop communication security by allowing strategic choices in quantum channel and teleportation strategyWe introduce an efficient and versatile quantum teleportation protocol for specific types of n-qubit entangled states.
