ABS | on: FAQ on Microsoft's topological qubit thing
what Microsoft claim in their marketing copy reported by the FT - for the average reader - and what a third-party, well-known expert in the field thinks... are on very different levels AFAIC

Microsoft is saying: we did it!

Everyone else is saying: prove it!

Yes, that's why we read decent journalism that includes the opinions of experts. MS are still saying production use is pretty far off.

except we don't need opinions, we need proof and that is what we are lacking.

The only expert in the FT article is Dr. Sankar Das Sarma who (from Wikipedia)

  "In collaboration with Chetan Nayak and Michael Freedman of Microsoft Research, Das Sarma introduced the ν = 5 / 2 topological qubit in 2005"
So you might understand why this FT article is not adding anything to the discussion, which does not discuss the theory but rather MS's claim of an actual breakthrough.

They show a chip, we'd like proof of what the chip actually does
