In yesterday's issue of the journal Nature there is a report that in my opinion is one of the most significant advances in the field of quantum computing. 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.
