TBH, I ignore her physics takes too. Her background is in the cosmology/quantum gravity corner of the subject. That’s a different specialization from the experimental implementation of quantum computers. And when she wandered into quantum foundations, a subject I’ve put a lot of work into understanding, her thinking came across as in part shallow, in part deliberately contrarian. So, yeah, Google is hyping their work — that’s a safe bet — and further progress is going to be harder than the sales talk makes it sound. But on the other hand, it’s possible to have “physicist disease” about other subfields of physics than one’s own.

(I have not had the time and energy to read the underlying paper in detail myself yet.)
