Please take me off this thread. I do not know why I am on it?

There seem to be two papers that have sparked the recent excitement. One involves boring old superconducting qubits. AFAIK, it assumes a significant improvement in noise performance to work. So the fact that it uses less qubits isn't very interesting in the absence of increased noise performance. Impossible is still impossible.

The other one involves something called neutral atoms. This technology has better noise performance. But it is a different technology. It appears that we don't know how to run a relevant algorithm on it at this time in a useful way. The paper refers to "engineering challenges". So I think this is the one to pay attention to in the next few months. We need to wait for comments from knowledgeable critics.
