Neat article. It is truly a testament to the genius of Feynman to have
been able to conceive of such a machine in the first place, and it
could be revolutionary for doing molecular dynamics simulations (which
are still really in the dark ages).
However, the one thing I didn't notice was any type of comparison to
what a conventional computer would do on this same problem (i.e
computing the energy levels of hydrogen). Even though the article
mentioned how a quantum computer having a modest number of qbits could
outperform a supercomputer, I didn't see anything that mentioned how
much faster or better the quantum computer was *on this specific
problem*.
