因?yàn)閷W(xué)校圖書(shū)館沒(méi)有數(shù)據(jù)庫(kù)，所以想求幫忙查一下SCI檢索號(hào)，題目是: A method of evaluating the quality of dual-path entangled quantum microwave signal generated based on von Neumann entropy 謝謝好心人啦！ @阿努 發(fā)自小木蟲(chóng)Android客戶(hù)端 |

https://apps.webofknowledge.com/ ... age=1&doc=1 A method of evaluating the quality of dual-path entangled quantum microwave signal generated based on von Neumann entropy 作者:Li, X (Li Xiang)[ 1 ] ; Wu, DW (Wu De-Wei)[ 1 ] ; Wang, X (Wang Xi)[ 1 ] ; Miao, Q (Miao Qiang)[ 1 ] ; Chen, K (Chen Kun)[ 1 ] ; Yang, CY (Yang Chun-Yan)[ 1 ] ACTA PHYSICA SINICA 卷: 65 期: 11 文獻(xiàn)號(hào): 114204 DOI: 10.7498/aps.65.114204 出版年: JUN 5 2016 查看期刊信息 ACTA PHYSICA SINICA 出版商 CHINESE PHYSICAL SOC, P O BOX 603, BEIJING 100080, PEOPLES R CHINA ISSN: 1000-3290 研究領(lǐng)域 Physics 摘要 The entangled state of continuous variables of microwave frequency is an important resource in the field of quantum. In order to apply it to quantum communication protocol and quantum radar, the entanglement between two spatially separated subsystems, namely dual-path entangled quantum microwave is needed. However, for the circuit that generates the entangled quantum microwave, there is no suitable method to indicate whether the quality of the entangled microwave signal is good or not. Aiming at this problem, we put forward a method of evaluating the quality of dual-path entangled quantum microwave signals generated based on von Neumann entropy. The origin of the entangled quantum microwave is that vacuum state signals are transformed into squeezed state signals in driven pump, so in this paper we use a two-mode squeezed vacuum state to describe the formation of dual-path entangled quantum microwave signal, thus providing the function relation between the photon number and the squeezed parameter. In a communication system, the signal-noise ratio is usually used to express the reliability of system. Entropy is a measure of disorder degree in information. If both of them can be made the analogy, the entropy is used to evaluate the proportion of entangled state signals, the quality of original signals will be evaluated and the relationship among the entropy and squeezed parameter and the photon number will be analyzed. The simulation results show that the photon number in the entangled quantum microwave signal is determined by the squeezed parameter, and there is an index change with the square rule between them. Entropy decreases with the increase of squeezed parameter: its minimum value is 0, and its maximum value can be found from 0.9 to 1. The slope of curve is steep near the maximum, which reflects that the influence of squeezed parameter on the degree of entanglement is obvious, and that the range of optimal value choices in squeezed parameter is very narrow. The optimal value of squeezed parameter is dependent on photon number; it increases with the increase of the photon number. Entropy tends to decrease smoothly with the increase of squeezed parameter and it approximately has a negative exponent relation. The photon number in an actual signal is limited, so the limit value of entropy is estimated to be about 65%. The research shows that the quality of the entangled microwave signal can be improved by choosing appropriate squeezed parameter in different circuits that generate dual-path entangled quantum microwave signals for meeting the actual needs. Therefore, the research can provide the method of choosing the parameters of dual-path entangled quantum microwave circuit and improve the availability of system. 關(guān)鍵詞 作者關(guān)鍵詞:entangled quantum microwave; von Neumann entropy; squeezed parameter; photon number KeyWords Plus:ELECTRODYNAMICS; INFORMATION 作者信息 通訊作者地址: Wu, DW (通訊作者) Air Force Engn Univ, Sch Informat & Nav, Xian 710077, Peoples R China. 地址: [ 1 ] Air Force Engn Univ, Sch Informat & Nav, Xian 710077, Peoples R China 電子郵件地址:wudewei74609@126.com 基金資助致謝 基金資助機(jī)構(gòu) 授權(quán)號(hào) National Natural Science Foundation of China 61573372 查看基金資助信息關(guān)閉基金資助信息 Project supported by the National Natural Science Foundation of China (Grant No. 61573372). 出版商 CHINESE PHYSICAL SOC, P O BOX 603, BEIJING 100080, PEOPLES R CHINA 類(lèi)別 / 分類(lèi) 研究方向  hysicsWeb of Science 類(lèi)別 hysics, Multidisciplinary文獻(xiàn)信息 文獻(xiàn)類(lèi)型:Article 語(yǔ)種:Chinese 入藏號(hào): WOS:000380364300017 ISSN: 1000-3290 其他信息 IDS 號(hào): DS1OB Web of Science 核心合集中的 "引用的參考文獻(xiàn)": 24 Web of Science 核心合集中的 "被引頻次": 0 JCR® 類(lèi)別 JCR 分區(qū) PHYSICS, MULTIDISCIPLINARY Q4 數(shù)據(jù)來(lái)自第 2015 版 Journal Citation Reports® |
