We need *one* QC Cray to calculate protein foldings or evolutionary
computation, and then we're home free. Ubiquitous QC seems unlikely,
not on grounds of expense, but on the grounds that a single KQb
(kiloqubit) will probably be enough to revolutionize the world beyond
where "ubiquitous" has any meaning.
"And the Lord said to Peter Shor: I COMMAND YOU TO BUILD A COMPUTER.
The height shall be three hundred qubits..."
