Quantum entanglement at n = 1 and N = 2

Nanxi Zou

Abstract Since the concept of quantum entanglement was proposed, quantum entanglement has been paid more and more attention. Especially in recent years, with the interdisciplinary and interdisciplinary development of quantum informatics, the general definition, physical properties and entanglement measurement of quantum entanglement have been comprehensively and deeply studied. Due to its nonlocality, quantum entanglement has been widely used in quantum information, especially in quantum communication. In view of the application status of quantum entanglement in quantum communication, this paper presents a survey of quantum entanglement and its application in quantum communication. In this paper, 230 staff members from 15 Chinese companies involved in quantum communication are selected as the investigation samples, and the proportion of quantum entanglement in the application is obtained, which can promote the quantum communication. The capacity, speed and security of quantum entanglement and ordinary quantum in the application of quantum communication are compared. Through the analysis, it is concluded that each index of quantum entanglement is conducive to the development of quantum communication. Quantum entanglement provides a technical guarantee for the research of quantum communication.

Quantum entanglement is an important phenomenon,and it can not be understood in classical physics.Quantum entanglement shows in both statistical mode and equational mode.Quantum teleportation and quantum entanglement swapping are the typical phenomena to recognize quantum entanglement.Quantum entanglement is of non-locality and reality,and it can be created and destroyed,and it is the unity of separation and non-separation.Quantum entanglement is extending new philosophical domain.
