To continue the discussion, anyone else notice that the big players have all within the last year or so entered the quantum gamble? All announcing some level of commitment to quantum as a part of their long-term strategy for the next 10 years? Some starting to roll out SDKs to grow public interest and develop an ecosystem.
What did they all know that the rest of us didn't? My hunch was that they knew quantum computing would become a mainstream technology. Was recently confirmed with some announcements these past couple of weeks. Bismuth-antimony (BiSb) thin-films are ideal topological insulators, that exhibit the quantum hall effect at room temperature, and are on track first for new applications with new memory tech. Topological quantum computing is the approach Microsoft is most focused on, as it has certain properties that make it really good at error correction with far less resources.

That should be enough time for BiSb to mature in the lab and the fab. Combine it with the 3D stacking used for HBM and we're looking some serious soykaf. Recall Alan Kay's ominous "the real computer revolution hasn't started yet" line.
