What is a “completely quantum mechanical state”?

Don’t know. I’m still amazed at the claim that it doesn’t have an initial temperature???

The article is so completely imprecise and oversimplified to be virtually meaningless, so I wouldn’t waste a lot of time on it.

The abstract and graphs at the article are briefer but contain a much better description. The experimentalists prepared a gas with all atoms in a specific state (you can do this because they're bosons.) They split the gas into two separated ensembles with their phases correlated. Over time, the phases become uncorrelated. The loss of correlation propagates through the gas with finite speed, despite (the claim by experimentalists) that there is no classical influence to de-cohere the states.

The gas in its final form is still quantum mechanical.
