CassandrichFolks do realize the people telling you QC will be a thing and break RSA and EC are exactly the same folks who were telling you AGI will be a thing, who were the exact same folks telling you the metaverse is the next big thing, who are the exact same folks telling you NFTs would take off, who were the exact same folks telling you bitcoin would replace Visa, who were....
Jackie@dalias quantum computing will not take off because quantum physics makes it almost impossible
cyberia@burnoutqueen @dalias how come? I'm about to embark on a PhD in PQC so would be good to know this!
There is no known way to create the quantum superpositions at the scale required in an economical way. For all I know, you would need extreme cooling and a vacuum chamber to minimize any and all interference with the outside environment.
Even a little vibration in the system can ruin the whole thing
David Chasteen@burnoutqueen @cyberia @dalias NSA doesn't care about economical. Didn't Snowden reveal that NSA already had an outsized investment in this a decade ago? If they're making progress they'll keep it secret as long as possible. The fact that USG is moving to PQE seems like an indicator of how legitimate they think the threat is.
@Chasteen @burnoutqueen @cyberia There's $10 trillion "not economical", there's all-of-the-earth's energy-reserves-for-100-years "not economical", and there's millions-of-dyson-spheres "not economical".
