Center node: "remarks on quantum modular exponentiation and some experimental demonstrations of shor s algorithm"
  Abstract: Abstract. An ecient quantum modular exponentiation method is indispensiblefor Shor’s factoring algorithm. But we nd that all descriptions presented by Shor,Nielsen and Chuang, Markov and Saeedi, et al., are awed. We also remark that someexperimental demonstrations of Shor’s algorithm are misleading, because they violatethe necessary condition that the selected number q = 2 s , where sis the number ofqubits used in the rst register, must satisfy n 2 q<2n 2 , where nis the large numberto be factored.Keywords. Shor’s factoring algorithm; quantum modular exponentiation; super-position; continued fraction expansion. 1 Introduction It is well known that factoring an integer ncan be reduced to nding the order of an integer xwithrespect to the module n(G. Miller [1]). The order is usually denoted by the notation ord n (x):So far,there is not a polynomial time algorithm run on classical computers which can be used to computeord n (x). In 1994, P. Shor [2] proposed the rst quantum algorithm which can compute ord
