: In any event, these researchers called on scientists around the world to
: develop ciphers resistant to attack by quantum computers.
To clarify: there is, of course, nothing odd about a quantum computing
researcher mentioning, in a public lecture, that quantum computers are
just around the corner, and it would be nice if this didn't lead to the
breakdown of privacy and security of on-line funds transfer and the like.
It was because the news item billed the pair, apparently incorrectly, as
*cryptography* researchers that their call to arms appeared strange, at
least based on _my_ understanding of cryptography, which may not be the
same as that of other people more versed in the field.
