"Observation of Bose–Einstein condensation of dipolar molecules" (2024) https://www.nature.com/articles/s41586-024-07492-z :

> Abstract: [...] This work opens the door to the exploration of dipolar quantum matter in regimes that have been inaccessible so far, promising the creation of exotic dipolar droplets [14], self-organized crystal phases [15] and dipolar spin liquids in optical lattices [16].


From TA:

> by tuning the microwave fields to allow some interaction between molecules, the team expects to see the system separate into quantum droplets, a new phase of matter. By confining the condensate in two dimensions using lasers, the team also hopes to watch while the molecules arrange themselves, under a microscope, to form a kind of crystal. “That’s something that has never been possible,” says Will.

> The condensate molecules could also form the basis of a new kind of quantum computer, adds Will. Given that each molecule is in an identical, known state, they could be separated to form quantum bits, or qubits, the units of information in a quantum computer. The molecules’ quantum rotational states — which can be used to store information — can remain robust for perhaps minutes at a time, allowing for long and complex calculations.

Coherent for perhaps minutes?
