Abstract

We describe a novel multi-particle, multi-degree entangled system in which one particle is entangled to other particles in different degrees of freedom. It allows efficient teleportation of a higher dimensional quantum state. We give a new protocol for quantum key distribution using this state and describe possible experimental realizations of the proposed QKD as well as the teleportation protocols.

Quantum Teleportation Protocol Based on Multi-Variable Quantum Entanglement

Jincheng Zhang

This paper proposes a novel quantum teleportation protocol leveraging multi-variable quantum entanglement. The core of the protocol relies on the strong correlations inherent in multi-dimensional entangled states to achieve high-efficiency and secure quantum teleportation. We demonstrate a framework for constructing such a protocol and analyze its potential advantages over traditional approaches. The key contribution lies in expanding the theoretical foundation of quantum teleportation, offering a new strategy for quantum communication and information processing. The protocol utilizes a series of Bell state measurements and classical communication to transfer the quantum state from one location to another, relying heavily on pre-shared multi-variable entangled pairs. We outline the mathematical formalism underpinning the protocol, including the description of the entangled states, the Bell state measurements, and the necessary classical information exchange. The protocol aims to enhance the transmission efficiency and bolster the security of quantum teleportation by exploiting the complexity and robustness afforded by multi-variable entanglement.

Quantum teleportation of incomplete multi-quantum systems

Ying Wu, Yuanfeng Jin, Yang Liu +1 more

Abstract This paper proposes a quantum teleportation scheme for incomplete multi-quantum systems. According to the structure of the transport state, the number and structure of the quantum channel can be determined, as well as the quantum circuit for quantum teleportation. Compared to previous quantum teleportation protocols, this scheme reduces both the number of qubits in the channel and the amount of classical communication required, thereby enhancing the efficiency of quantum teleportation. Furthermore, this approach offers a new path for constructing non-maximally entangled state channels, which is beneficial for building complex quantum networks and enabling Multi-party quantum teleportation.
