POLYNOMIAL-TIME ALGORITHMS FOR PRIME FACTORIZATION
... Abstract. A digital computer is generally believed to be an ecient universal computing device; that is, it is believed able to simulate any physical computing device with an increase in computation time by at most a polynomial factor. This may not be true when quantum mechanics is taken into consid ...
