The paper's abstract has indicia of crankery, and the public state of the
art involves some dispute over whether current quantum computers can
efficiently factor two-digit numbers.

Like is said in the article:

It would be easy to impress everyone by finding the factorization of any
currently unfactored RSA number.

The results would be less than a paragraph of text in length, and easy
for anybody to check.  There are also dozens of practical options for
establishing priority of discovery.
