This has been on the arxiv for several months. Like most of Google's work in this field, it's very impressive and pretty important from an R&D perspective (as far as I can tell from skimming it last year). Also, don't freak out, because one logical qubit doesn't exactly mean that we're just months away from the thousands or millions we need for something like Shor's algorithm.
