Here's my attempt at distilling it:

"Normally in a quantum computer, if we apply measurement function F to input x so y=F(x), it's impossible to reverse F and turn y into x. However, if we constrain y, we can make a special function G_Y such that x=G_Y(y)"

Whilst I don't have time to really dive through all the sections, this seems weirdly click-baity and IBM-promoting for an academic article.
