An optical tweezer array of ultracold polyatomic molecules
Polyatomic molecules have rich structural features that make them uniquely suited to applications in quantum information science1–3, quantum simulation4–6, ultracold chemistry7 and searches for physics beyond the standard model8–10. However, a key challenge is fully controlling both the internal quantum state and the motional degrees of freedom of the molecules. Here we demonstrate the creation of an optical tweezer array of individual polyatomic molecules, CaOH, with quantum control of their internal quantum state. The complex quantum structure of CaOH results in a non-trivi...
