Comment on "Quantum Multiplexer Designing and Optimization Applying Genetic Algorithm"
The authors have noticed that many fundamental laws and rules of quantum-circuit are violated in a work published in International Journal of Computer Science Issues. The authors of this published paper presented a quantum multiplexing circuit which is composed of half-adders, i.e. quantum multiplexing functionality is claimed to achieve by using few units of quantum half-adder. The authors performed 'Qubit copying', 'Fanout' etc. in the quantum circuit which are prohibited. Apart from these, two quantum circuits are claimed to be equivalent to each other though their operational matrices are not same.
