Comments on “Quantum Classification Algorithm Based on Competitive Learning Neural Network and Entanglement Measure”

Abstract

In a paper on competitive learning neural network, Mohammed Zidan et al. (Applied Sciences 9.7 (2019): 1277) proposed a new algorithm for the entanglement classification of two qubit states using the competitive learning and quantum computation. In this letter, we claim that the result after statement “the state of the two-qubit system…” in step 3 of the section “Classification an Input Using the Proposed Algorithm” in this manuscript is wrong.
