Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0042] Such as figure 1 Shown: a method for establishing a quantum channel and transmitting quantum information for a wireless self-organizing quantum communication network, comprising the following steps:

[0043] (1) Perform entanglement exchange from the adjacent nodes of the source and destination nodes, and transfer the measurement results to the next node along the direction of the intermediate node;

[0044] (2) The node judges whether the measurement results from two directions are received; if so, the last entanglement exchange is performed at this node, which will entangle the two unentangled particles in the source node and the destination node, and establish the source and destination Quantum channel between nodes, skip to step (3), otherwise perform entanglement exchange, transfer the measurement result to the next node along the direct...

Abstract

The invention discloses a method for building quantum channels and transmitting quantum information in a wireless self-organizing quantum communication network, comprising the following steps of: (1) performing entanglement exchange from the adjacent nodes of a source node and a destination node, and transmitting the measurement results to the next node along the direction of the middle node; (2) judging whether receiving the measurement results coming from two directions by the node; (3) respectively transmitting the particle entanglement states of the source node and the destination node corresponding to the measurement to the destination node and the source node by the node through wireless channels; and (4) after receiving the measurement results, transmitting the quantum states of the carried information through quantum remote teleportation by the source node so that the quantum states of the carried information can be transmitted to the destination node. The method provided by the invention can obviously save the cost of wireless transmission for building the quantum channels and transmitting the quantum information, can reduce the data packets to be transmitted by the wireless channels, and can reduce the collision probability of the data packets in the wireless channels.

Description

technical field [0001] The invention relates to quantum communication and information dissemination technology, in particular to a method for establishing a quantum channel and transmitting quantum information in a wireless self-organized quantum communication network. Background technique [0002] Quantum teleportation is a brand-new communication method, which uses entangled quantum pairs shared by both parties to transmit quantum information. Because of its non-locality, irreversibility and instantaneousness, it is widely used in quantum communication networks. On the basis of quantum teleportation, multi-node long-distance communication can be realized by combining entanglement exchange and entanglement purification. In 1993, using the concept of quantum entanglement, he proposed the theoretical scheme of quantum state teleportation and realized quantum teleportation. In 1993, a quantum entanglement exchange scheme was proposed based on quantum teleportation. Quantum r...
