Wrong. The number of Qbits is not scaling. It is slowly very going up. It would need to go up double-exponentially (!) to even give us liner improvement in computing power per unit of time. It does not even go up linearly with time, it is _slower_. Hence we will never even see enough effective Qbits that can stay entangled long enough to attack currently secure cryptography. The Sun will explode before that happens.
That said, QCs will _never_ break AES256. This universe is to small for that aver happening. The QC effort for that is 2^128 and no computing mechanism will ever be able to do this number of steps.
What really astonishes me how confidentially clueless people like you are. You do not even understand the basics and yet you make gande claims.
