Especially the presence of controllable non-conservative processes in optical and photonic systems has triggered the development of singularity-based sensing. By flexibly tuning gain, loss, and coupling strength, a series of high-resolution sensing approaches can be realized, with the potential of on-chip integration. Another important non-Hermitian singularity is the coherent perfect absorption-lasing (CPAL) point in the PT-broken phase, which manifests the coexistence of lasing and CPA, exhibiting intriguing properties with considerable sensing potential. As a crucial method for quantum sensing and metrology, the interaction between light and alkali-metal atomic ensembles promises unprecedented sensitivity in the measurement of ultra-weak magnetic field, inertia, and time. Therefore, extending the study of PT-symmetry and singularity-based sensing from conventional solid-state wave systems to diffusive systems such as atomic ensembles is attracting wide attention. In this review, the development of singularity-based sensing in PT/anti-PT symmetric non-Hermitian systems is summarized, with a special focus on photonic platforms including integration with waveguides, microcavities, metasurface, etc. In addition, sensing applications with discussion further extended to atomic ensembles, projecting future research trends in the field.</p>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"8 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119729","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}
