Ato­mic devices for timing, field sens­ing and com­mu­ni­ca­ti­on have been demons­tra­ted in pro­to­ty­pes ope­ra­ting in field and space envi­ron­ments. Howe­ver, trans­fer into fur­ther minia­tu­ri­zed sys­tems with hig­her sta­bi­li­ty, less com­ple­xi­ty and the poten­ti­al of sca­lable manu­fac­tu­ring remains a major tech­no­lo­gi­cal chall­enge. In the Joint Lab Inte­gra­ted Quan­tum Sen­sors (IQS) of Fer­di­nand-Braun-Insti­tut and Hum­boldt-Uni­ver­si­tät zu Ber­lin, we deve­lop the next gene­ra­ti­on of inte­gra­ted ato­mic devices for real world appli­ca­ti­ons.
