原文开头
Yifan Li1†, Lex Joosten1, Youcef Baamara2, Paolo Colciaghi1, Alice Sinatra2*, Philipp Treutlein1*, Tilman Zibold1 In quantum metrology, entangled states of many- particle systems are investigated to enhance measurement precision of the most precise clocks and field sensors. Whereas single- parameter quantum metrology is well established, joint multiparameter estimation poses conceptual challenges and has been explored only theoretically. We experimentally demonstrated multiparameter quantum metrology with an array of entangled atomic ensembles. By splitting a spin- squeezed ensemble, we created an atomic sensor array featuring intersensor entanglement that can be flexibly configured to enhance measurement precision of multiple parameters jointly. …
