Any idiot with a two state system thinks they have a Quantum Computer, but this is different. Non-Abelian braiding statistics are so far the only known robust architecture for QC, so this will be interesting to watch. Its worth mentioning that the cocktail they discuss relies on something that has yet to be observed in nature; calling it science fiction would be an insult to time travel.
I'm not sure "non-Abelian braiding statistics" is the only known robust architecture for QC. Topological qubits are, after all, just systems whose natural states are quantum error correcting codes. Those who chose to pursue quantum error correction directly likely also deserve the moniker of "robust architecture".
