In point of fact, we don't know this.

Theoretically, science-fiction level breakthroughs in quantum
computation would break RSA.  But the problem with theory is some of the
things that theory permits turn out to be impossible in reality.  For
instance, there's nothing in the laws of physics that prohibit things
from having negative mass, but we've never encountered negative-mass
material anywhere: not in the lab, not in the world, not in deep space,
not anywhere.

It's good to be skeptical of quantum computation.  It's interesting to
read up on, but be immensely skeptical of all predictions.
