These quantum computers do not actually do what you think they do. they aren't conventional function computers but probability solvers for formations of solutions. they are very epotomy of asics but not for definitive maths.

they do not do standard mathematics and cannot be switched over. they short cut high difficulty pattern and lowest energy state problems in a noisy quantum way. they are not good at high grade parallel math. they effectively act like little distillery pots for patterns or lowest energy configurations of a problem, like folding or crystal lattice problems.
