Kvantdatorer är som grafen, det har snackats om det i evighet, men det verkar aldrig komma ut något användbart.

Du har en poäng... Det handlar om kanske åtskilliga decennier utan en fungerande produkt på marknaden eller som ens vetenskapen kunnat använda ordentligt.
För några år sen hävdade dock Google de nått en milstolpe...

Our Sycamore processor takes about 200 seconds to sample one instance of a quantum circuit a million times—our benchmarks currently indicate that the equivalent task for a state-of-the-art classical supercomputer would take approximately 10,000 years. This dramatic increase in speed compared to all known classical algorithms is an experimental realization of quantum supremacy8,9,10,11,12,13,14 for this specific computational task, heralding a much-anticipated computing paradigm

Fast kineser hävdar de senare gjort samma sak genom att bara simulera en kvantdator.

Zhang’s group claims to have done it in 15 hours. And if they had access to a proper supercomputer like Summit, it might be accomplished in a handful of seconds — faster than Sycamore. Their paper will be published in the journal Physical Review Letters; you can read it here (PDF).
