Rigetti Computing
“Rigetti spent a decade building what might be the most legitimately impressive technology that almost nobody can actually use yet — superconducting quantum processors cooled to one-hundredth of a Kelvin, fabricated in their own foundry, accessible through AWS and Azure. The problem is they're selling picks and shovels for a gold rush that keeps getting delayed by another 'breakthrough in error correction,' while classical AI just solved most of the optimization problems quantum was supposed to tackle first.”
