I'm not sure what's supposed to be publication-worthy here. This is common knowledge for anyone who's ever interacted with sheep on a farm, in their natural, fermionic superfluid state. If you turn over a sheep and tickle its ticklish underbelly, you get a sheep-laugh (a hilarious sound) only about 50% of the time; the other 50%, you'll hear a sheep laughing from the opposite end of the meadow. Because, you cannot definitively say if it was *this* sheep you tickled, or *that* other, identical one. They are indistinguishable baa-tickles
Even if something is well known, its important to measure it and set statistical limits. While the 4 sigma in the article is not enough to claim an observation, it opens the points towards some exciting new Beyond the Shearing Model physics.
It's interesting that they noticed it right in the vicinity of the LHC, maybe this hints at some kind of leak?
The one in my garden always watches me through the window then I turn on the vacuum, so maybe it's feeling some kind of oddity with the electric motor. It's an old 3500 Watts one, which is now illegal to sell, and badly shielded.
So sheep are fermions? Is that why you can't have two sheep at the same place in the state? (up and down sheep can be stacked no problem, there's plenty of empirical evidence of this)
+1 for lack of surprise, but that's very interesting about the tickle - must be a lot of fun
Tickle entanglement in sheep cannot be used for signaling however because of Bell's theorem.
Bell's theorem basically states that the state of a sheep's neck bell cannot be influenced by tickling.
I am somewhat rusty on my undergrad quantum, but I'm not entirely sure I agree with this analysis. Could you perhaps explain it more clearly in baa-ket notation?
