Funny, "like miniature Rockettes" is exactly how Donatello visualizes quantum particles.

Good article. Tad confusing.

The "cat state" refers to the famous "Schrödinger's cat" thought experiment, which was intended to show that, according to the math, all states exist at the same time and also that such a thing is crazy. The cat is equally alive and dead, or in this case it's spinning in both directions. This impossibility may be attributed to the our sketchy understanding of quantum mechanics... which is what the physicists quarrel about in the article. Either these things really ARE happening or we're missing something.
