Comment on Demonstrations of Shor's Algorithm in the Past Decades.
Zhengjun Cao, Zhenfu Cao, Lihua Liu · 2015
Abstract. We remark that the experimental demonstrations of Shor’s algorithm in the past decades are falsely claimed and flawed, because they had used too less qubits in the first quantum register to accomplish the step of Continued Fraction Expansion in Shor’s algorithm. More worse, the amount of qubits used in some experiments are too less to represent all residues modulo n, which means that the number n cannot be truly involved in the related computations.
