I really hope they succeed with this. However, the fact that they are publicly offering $5M to someone, ANYONE, who can think of a real world use case for these things as they currently exist does not inspire confidence. And Google has certainly acquired a reputation for killing projects these days.
Milestones 4-6 (ending up with 6 at 10^6 qubits) aren't given an ETA.<p>For those more familiar with the field, what are the chances we have million qubit quantum computers a decade from now? Too early to tell?
