Yes, that was a whole pile of marketing-engineering fluff that never made an attempt to explain what they had accomplished. The links in the article don't help either. They did hit climate change, though.

They stated that the qubits they are working with are topological defects similar to knots. OK, but defects in the topology of what? Spacetime? The Maxwell potential? Hilbert phase space?

How many topological qubits are needed to produce a logical qubit?

Then they mentioned nanowires connecting the topological qubits. Are those just tiny wires, or is there a quantum phenomenon associated with them? How is the readout done? I assume it's destructive?

As an aside, with all the subtle research being done on qubits and entanglement, I would have expected some clarity in the fundamental interpretation of QM by now (Copenhagen, Manyworlds, Bohmian), but I haven't heard of anything new for awhile.
