coherence times

From the article "IBM's Q Systems cannot attain coherence times (the time before the quantum states relax into an answer) of over 90 microseconds, allowing their 20-to-50 qubit systems the time to solve extremely complex applications impossible for conventional supercomputers." Did you mean "cannot"?  Otherwise, what coherence times are acheivable and what can be solved?

Thanks for the correction, it sould read: "IBM's Q Systems can attain coherence times (the time before the quantum states relax into an answer) of over 90 microseconds, allowing their 20-to-50 qubit systems the time to solve extremely complex applications impossible for conventional supercomputers.
