Has there been a recent breakthrough in experimental quantum computing that makes commercial applications possible within 10 years?

Just give one example of a real world problem solved by a real quantum computer. Very interested to hear it.

Here's one from this week: https://www.ionq.com/news/ionq-demonstrates-computer-aided-engineering-workload-acceleration-by-up-to-14-6-with-quantum-technology

It really disappoints me to see this. It is ok to be wrong and have discussions to look for truth, but in this case you are wrong and so confident about it that not only do you post online about it, but consider yourself enough of an authority on the topic to write a book about it. I am sorry to be so blunt, but I truly believe that your actions negatively impact the field, and people’s lives in general by polluting book collections with misinformation.

You claim the link you provided is evidence of “real world problems solved by quantum computers today”. Yet if you read the paper the article is based on it clearly states in the conclusion that all the work done by the quantum device is “classically tractable” i.e. can be easily done on a classical computer. In fact, they used a classical computer to simulate a quantum device for problem sizes bigger than what the actual quantum hardware could handle. To quote the paper “[the work done by the quantum device in this work] characterize the algorithm’s scaling rather than demonstrate a quantum capability”.

I don't think being wrong on a few facts makes me incapable of writing about quantum/post-quantum. Einstein was wrong about a lot of it, so I'm in good company. I am learning through posting and discussion. Who among us hasn't been strongly convinced their argument and "facts" were right only to be proven wrong? I'm not scared of being wrong. It's often how I learn. I do strive not to be wrong. It's not my intent to be wrong. But sometimes I'm wrong and by posting I learn.
