P = some degree of computational power
A = some small unit of P, like a laptop
B = the largest unit of P practically
possible under the same laws of physics as A
(data encrypted by A cannot be "cracked" by B in a reasonable amount of time)
so in my head, so long as a normal civilian can access qubit technology (likely questionable), encryption still works by increasing the number of rounds. what am i missing?
you can cheat by adding trailing spaces
