Thanks. What I get is that a quantum computation is an extremely dynamic thing, and the main 
takeaways are:

1. You have to believe, for reasons of physics, that the chip is actually behaving in the way you 
think it is behaving. But you can't actually tell. The reasoning is all indirect, not observational.

2. The "answer", if you get one, exists only fleetingly. And you cannot actually read it. It is 
characterised by the manifestation of a specific phenomenon. For an instant. You just believe, for 
good reasons of physics, that the phenomenon you call the answer did in fact manifest for an instant.

3. The key "advance" in this case is that the answer lasted longer than the inputs, for what Google 
is claiming is a first time.

Is this right?
