Reading the current Science article on this topic I got the impression that ‘quantum advantage’ might be a more reasonable first goal. that is we are still waiting for a quantum computer which can perform better than an ordinary computer in a single restricted setting. Also I was a little bit shocked that even with 16 Qbit those systems already show a significant error rate (I think up to 50%) My skepticism was confirmed by estimates in the same article of the Quantum supremacy still being decades away. So I’m a little bit confused about the current announcement but fortunately it is easily falsifiable... let’s wait for 2020
