John, isn't it a wiser thing to consider impact over capability? Maybe this is my hang up, but if your QC's solves medical problems or energy problems, rather than the Gee Whiz of mere computational prowess. Yeah, prowess should lead to the things I cited. But then in the 1950's the immensity of nuclear fission over carbon burning should have led to an Atomic Age, but it didn't.

Scientists not only used a scanning tunneling microscope to make a functional quantum processor that is composed of 10 quantum dots placed with sub-nanometer precision by a scanning tunneling microscope, they tested it by modeling how electrons move along a polyacetylene molecule, a task conventional supercomputers would have great difficulty with even for a molecule as simple as polyacetylene. A penicillin molecule only has 41 atoms but a classical computer would need to have 10^86 transistors to make a quantum mechanical model of it. There are only 10^80 atoms in the observable universe. A quantum computer would only need 286 logical qubits to do the same thing; yes those 286 would need to be high-quality qubits but thanks to quantum error correction they don't have to be perfect.
