  The RSA cryptosystem could be easily broken with large scale general purpose
quantum computers running Shor's factorization algorithm. Being such devices
still in their infancy, a quantum annealing approach to integer factorization
has recently gained attention. In this work, we analyzed the most promising
strategies for RSA hacking via quantum annealing with an extensive study of the
low noise D-Wave 2000Q computational times, current hardware limitations and
challenges for future developments.
