Everything you've been posting is technically correct whereas the parent was technically incorrect, but it's still huge progress and an important step. No, they're not at the useful stage yet, but we can see now that it's inevitable, whether it's years or decades away.
- lisper 7y agoYes, it's huge progress, but huge progress != useful. And getting to useful, while very likely a matter of when and not if, is not inevitable. The number of qbits in current technology is measured in the dozens whereas the number of qbits needed to do something useful is likely in the thousands (because error correction will almost certainly be needed). QCs don't scale like CCs do. There could be some pretty significant obstacles between here and useful. C.f. fusion power, which has been 10 years away from being useful for about 40 years now.
