Newbie's question: how far is the RCS benchmark from a more practical challenge such as breaking RSA?
The article concludes by saying that the former does not have practical applications. Why are they not using benchmarks that have some?
There are already companies selling 5,000+ qubit quantum systems to the NSA. I would assume they are already using it for that in the huge data center in Utah.
Very far.
I'm not sure how to put it quantitatively, but my impression from listening to experts give technical presentations is that the breaking-rsa-type algorithms are a decade or two away.
This is very soon from a security perspective, as all you need is to store current data and break it in the future. But it is not soon enough to use for benchmarking current systems.
