  Quantum computing is of high interest because it promises to perform at least
some kinds of computations much faster than classical computers. Arute et al.
2019 (informally, "the Google Quantum Team") report the results of experiments
that purport to demonstrate "quantum supremacy" -- the claim that the
performance of some quantum computers is better than that of classical
computers on some problems. Do these results close the debate over quantum
supremacy? We argue that they do not. We provide an overview of the Google
Quantum Team's experiments, then identify some open questions in the quest to
demonstrate quantum supremacy.
