The red sponge has a surface protein that has a molecular weight of more=20
than 1'000'000 u. So you just keep adding CH_2 groups to the molecule?

Don't think Moore's law only holds for silicon chips. Expect the=20
register size of QC's to equally grow exponentially. But since QC's=20
operate on all possible values of the register at once, you only need=20
to push the regster size to 4k bits. If you reached that, 128kbits will=20
be doable, too. Imagine how long a silicon computer needs to even=20
create auch a key...
