--- res: bibo_abstract: - Compact and robust cold atom sources are increasingly important for quantum research, especially for transferring cutting-edge quantum science into practical applications. In this study, we report on a novel scheme that uses a metasurface optical chip to replace the conventional bulky optical elements used to produce a cold atomic ensemble with a single incident laser beam, which is split by the metasurface into multiple beams of the desired polarization states. Atom numbers ~107 and temperatures (about 35 μK) of relevance to quantum sensing are achieved in a compact and robust fashion. Our work highlights the substantial progress toward fully integrated cold atom quantum devices by exploiting metasurface optical chips, which may have great potential in quantum sensing, quantum computing, and other areas.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Lingxiao foaf_name: Zhu, Lingxiao foaf_surname: Zhu - foaf_Person: foaf_givenName: Xuan foaf_name: Liu, Xuan foaf_surname: Liu - foaf_Person: foaf_givenName: Basudeb foaf_name: Sain, Basudeb foaf_surname: Sain - foaf_Person: foaf_givenName: Mengyao foaf_name: Wang, Mengyao foaf_surname: Wang - foaf_Person: foaf_givenName: Christian foaf_name: Schlickriede, Christian foaf_surname: Schlickriede foaf_workInfoHomepage: http://www.librecat.org/personId=59792 - foaf_Person: foaf_givenName: Yutao foaf_name: Tang, Yutao foaf_surname: Tang - foaf_Person: foaf_givenName: Junhong foaf_name: Deng, Junhong foaf_surname: Deng - foaf_Person: foaf_givenName: Kingfai foaf_name: Li, Kingfai foaf_surname: Li - foaf_Person: foaf_givenName: Jun foaf_name: Yang, Jun foaf_surname: Yang - foaf_Person: foaf_givenName: Michael foaf_name: Holynski, Michael foaf_surname: Holynski - foaf_Person: foaf_givenName: Shuang foaf_name: Zhang, Shuang foaf_surname: Zhang - foaf_Person: foaf_givenName: Thomas foaf_name: Zentgraf, Thomas foaf_surname: Zentgraf foaf_workInfoHomepage: http://www.librecat.org/personId=30525 orcid: 0000-0002-8662-1101 - foaf_Person: foaf_givenName: Kai foaf_name: Bongs, Kai foaf_surname: Bongs - foaf_Person: foaf_givenName: Yu-Hung foaf_name: Lien, Yu-Hung foaf_surname: Lien - foaf_Person: foaf_givenName: Guixin foaf_name: Li, Guixin foaf_surname: Li bibo_doi: 10.1126/sciadv.abb6667 bibo_issue: '31' bibo_volume: 6 dct_date: 2020^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/2375-2548 dct_language: eng dct_publisher: American Association for the Advancement of Science@ dct_title: A dielectric metasurface optical chip for the generation of cold atoms@ ...
