I presume neutrino decoherence is minimal, but would like to have some idea of timescales. Also curious about the effect of neutrino oscillations on this.

Anyone know how well neutrino would function as a quantum wire (i.e., store of quantum information)?

Neutrino oscillations could be awfully problematic if the quantum info was encoded in flavor eigenstates(+mass mixing). We had a lengthy discussion re using neutrino qubits at IQC some years back. There were measurement + state evolution issues. I'll see if I can find my notes.

To be clear, I think they're likely to be terrible qubits! The point is something can have a very long coherence time, and still be a horrid qubit.

If you can't get information into or out of a neutrino reliably, it doesn't matter how well it transmits it, it's not an information medium.
-
Yes, I know. That's one of the main points of the couple of paragraphs I'm writing.

Neutrino is very difficult to manipulate! Difficult to detect.

If you can’t store information with it, use it as art you might get >400g in an auction, then use the money to find more interacting particles, just don’t publish anything before the auction otherwise other people will get the money
