I think one of the killer apps is the purpose Feynman originally envisioned – simulating quantum systems: https://people.eecs.berkeley.edu/~christos/classics/Feynman.pdf https://people.eecs.berkeley.edu/~christos/classics/Feynman.... I wasn't able to dig up too much, but the introduction to a paper [1] by some Google folks provides a bit of insight into what might be possible: > In particular, quantum simulation of molecular energies, which enables numerically exact prediction of chemical reaction rates, promises significant advances in our understanding of chemistry and could enable in silico design of new catalysts, pharmaceuticals, and materials.
