I know little, but wasn’t microsoft hawking some quantum accelerator chip a while back? It was a card like a GPU that you put into a regular PC’s expansion slot to do quantum calculations. Expensive (a few thousand) and still niche but seemed like a good enough proof of concept that you can mass manufacture these things
it was built off a theoretical particle (majorana) and as always they conveniently left out some things so from what i remember the chip was fundamentally useless because it barely worked in practice and the existence of the particle it was built on is still very dubious (aka we’ve got no proof it’s actually a thing). read more here
