AIMS: an AI experimentalist turns uncertainty into quantum matter discovery

Siyuan Qiu, Philip D. Suh, Nhat Huy Tran +13

Most AI agents act only after scientists have defined the task. Discovery is harder under practical uncertainties: the probe may not be where it is expected, the signal may occupy…
