comment Assuming a 1024qb quantum computer, how long to brute force 1024bit RSA, 256bit AES and 512bit SHA512
For 5: No, it will not take twice the time as a quantum computer must handle all at once and will not be able to be of any use in your case.

@king_julien That's it. The difficulty to brute force the parts is the basic security of such algorithms. Also there is no inverse for $m^a \mod p$ which makes it difficult to brute force the algorithms.
