Improving Shor’s Algorithm

We dont have a useful quantum computer yet, but we do have quantum algorithms. Shors algorithm has the potential to factor large numbers faster than otherwise possible, which--if the run times are actually feasible--could break both the RSA and Diffie-Hellman public-key algorithms. Now, computer...
