Anyone can post on arxiv.
Quantum computation is reversible in terms of applying unitary gates to qubits.
However doing IO - breaking entangled states, or interacting with the outside world, is not reversible in a practical sense.

- scottlocklin 8y agoLike classical reversible computing (which theoretically can mean P=NP), quantum computation fails to exist in the actual world; probably for the same reasons. I think it's not quite true anyone can post on arxiv, and I wager 10 quatloos that this goes into some non-obscure physics journal and is presented to great acclaim, despite being as dumb as a bag of hammers.
