In article number 2400237, Ralf Wunderlich and co-workers use a commercially available charge integrator IC with switchable input on a printed circuit board (cover image) for low-noise current measurements with a resolution of about 100 fA. Thus, the authors can image and detect small numbers of individual defects in ultrapure diamond. Furthermore, the authors conduct photocurrent-detected magnetic resonance (PDMR) on NV centers. The work paves the way for low-cost, miniaturized, simple and time-resolved photocurrent measurements of solid-state defects.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":72073,"journal":{"name":"Advanced quantum technologies","volume":"7 12","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/qute.202470035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142868346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how to achieve the chiral interaction between light and mechanical oscillators and explore the applications of the chiral optomechanical systems are still difficult encountered in cavity optomechanics.
