Let $\mathcal A$ be the hypothetical algorithm in the question, with input $(n,q)$, output $r$, such that $r^2\equiv q\pmod n$ for a $1/(\log(n))$ fraction of the quadratic residues $q\pmod n$, running in random polynomial time w.r.t. $\log(n)$, restricting to $n$ product of two large distinct primes. Let $\mathcal F$ be the following algorithm with input ...
