For example, factorizing a 2,000bit number in one day, a task believed to be intractable using classical computers, would take 100 million qubits, even if individual quantum operations failed just once in every 10,000 operations.What kind of operation counts are they assuming, and what kind of quantum error correction? Calderbank, Rains, Shor, & Sloane get (seemingly) quite good error correction without spending too many qubits, and the threshold theorem should let us patch things together... but the Martinis group are the real experts here, so if this is what they say there are good reasons for it.

I find it interesting how they held off on this until Windows 7 was no longer supported.

And also I read, the older versions of Windows don't support the ECC crypto so are not affected. Last fiddled with by retina on 20200116 at 10:38
