[QUOTE="-jeffB, post: 2665247, member: 27832"]Good catch, Jim! A couple of key observations from the article: They [I]hope to[/I] demonstrate [I]a[/I] computation that exceeds the capabilities of classical computers. It hasn't happened yet. It may happen soon. Probably. That's a 20-qubit computer. Startups are targeting 32 or 64 qubits Real Soon Now. Cracking 2048-bit RSA, the currently recommended standard, will require a machine with [I]thousands[/I] of qubits. Building a machine with that many qubits, that will keep them all superposed long enough to perform the computation, is [I]really really hard[/I] -- probably even beyond the resources of the NSA at present. If someone (perhaps one of Them) [I]does[/I] develop a machine capable of that kind of computation, a decade or more ahead of its expected arrival... well, Bitcoin is beyond small potatoes at that point. More like a single stray grain of rice.[/QUOTE]
