A few things to keep top of mind: Topoconductor is a word that they made up that isn't a technical term in the field or in any adjacent fields. It's stupid and you shouldn't say without rolling your eyes. Whoever came up with it should feel deeply embarassed for their role in this stupidity. There are way way way more than three phases of matter and we've been discovering and classifying them for >100 years at this point. So even talking about liquid gas and solid in the article/title is moronic. Creating Majorana quasiparticles has a long history of false start and retracted claims (discovery of Majoranas in related systems was announced in 2012 and 2018 and both were since retracted). The quoted Nature paper is about measurements on *one* qubit. One. Not 100, not 1000, a single qubit. Unless they think they can scale this up really quickly it seems like its a very long (or perhaps non-existent) road to 10^6 qubits. If they could scale it up so quickly, it would have been way more convincing to wait a bit (0-2 years) and show a 100 or 1000 qubit machine that would be comparable to efforts from Google, IBM, etc (which have their own problems).
