heinrich66: The only reason why the Internet fawns all over Neil deGrassi High Tyson is because he's black. The Internet thinks this is some sort of karmic perfection: black astronomer.I SAY fark ALL THE farkING farkERS
Copper Spork: Floating point ... it's by far the most used type of number in data processing.
cman: FTA:The rub is building even a single qubit is difficult. When you look at - i.e. read information from - a quantum system, it decoheres. In other words, it turns into an ordinary bit capable of holding only a single value. It ceases to be a quantum computer.We have yet to be able to counter the observer effect. How in the fark are we supposed to build a quantum computer when we can't even handle that?
abb3w: 512 qbits would seem to imply any crypto system using fewer bits than that for the key is now breakable, even without resorting to rubber-hose cryptanalysis.
heinrich66: Felgraf:./And without also bandying about theories like string theory and many-universe theory as though they are accepted scientific fact like Brian Greene seems to.You're nothing but a black apologist.
neongoats: So maybe you make 400 of them work the travelling salesman job in parallel and set one to thinking about which of the 400 is going to provide the best result.
Copper Spork: Stibium: Only integers and ratios give you exact solutions. Floating point arithmetic is nothing but an approximation, and it's by far the most used type of number in data processing.No, not that kind of "approximation" (and incidentally, floating point is exact, but not precise). The "it can't guarantee it's given you an optimal solution" kind of approximation. It can't, for example, give you the best solution to a travelling salesman problem. It can only give you a probably-quite-good solution.

Copper Spork: abb3w: 512 qbits would seem to imply any crypto system using fewer bits than that for the key is now breakable, even without resorting to rubber-hose cryptanalysis.The chip isn't programmable, can only solve one specially-designed problem, is only capable of approximations, not exact solutions, and has less processing power than a Xeon Phi.
