It has been widely used in the security, medicine, and environment fields these years. Detection of atoms and molecules at the nanoscale is one of the practical usages of optical microcavity. In this paper, we focus on a ultra-high-quality factor optical microcavity of whispering gallery mode (WGM) to detect the explosive of cyclotrimethylenetrinitramine (RDX). To demonstrate the high sensitivity of the method, we detect the solution at different concentrations. Different types of optical microcavities are suitable for the detection of different matters. Considering the effects of the results and the simplicity of operation, we use silica microspheres chiefly. This is the first time to detect the explosive using highly sensitive optical microcavity. The detection of pure explosives will be helpful for establishing the database of the explosives.","PeriodicalId":515700,"journal":{"name":"Quantum Engineering","volume":"143 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140256527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, these substances, such as chemicals, are housed within warehouses or laboratory facilities, making strict control over any unauthorized entry. The control can be achieved through various measures, including access control systems, registration systems, remote inspection and surveillance, and personnel checks. Given its essential significance, the security of surveillance system data transmission plays a critical role. On the one hand, authorized entities must be capable of detecting any malicious data interception, and on the other hand, confidential information must remain safeguarded when an eavesdropper is identified. To address transmission security, we have developed a quantum-communication-based system for transmitting surveillance imagery of the hazardous chemical storage area entrance. This system effectively thwarts eavesdropping and data tampering during transmission, thereby enhancing the security of conventional monitoring systems.","PeriodicalId":515700,"journal":{"name":"Quantum Engineering","volume":"24 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139445418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
