On his blog, Sigfpe has proposed SIGFPE’s Law, that unlike the exponential growth of ordinary computers, the number of qubits in a quantum computer will only grow linearly. So when the mafia hacks into your bank account a la Sneakers because of their quantum public-encryption-cracking supercomputer, blame Sigfpe for getting it so terribly wrong. Also, blame him for the lack of flying cars.

(One subtlety to keep in mind — which Sigfpe alludes to — a 2-qubit computer is not the same thing as 2 1-qubit computers. The the states of each qubits must allow quantum superposition with each other to really count.)
