Depolarizing channel on the Deutsch-Jozsa and quantum counting algorithm using Qiskit / Pio L. Fortuno, III, Luis Gabriel Q. del Rosario, Henry N. Adorna.

A novel method based on the Qiskit Python framework is used on the Deutsch-Josza and quantum counting algorithms. This method uses a classical method to randomly place depolarizing channels in the form of X, Y, or Z quantum gates inside the quantum circuit, randomizing the locations for each trial. This method bypasses the quantum circuit implementation of the depolarizing channel by implementing the effect of the channel should it take affect on the circuit, instead of using its superposition. The method has shown that the superposition of measurements of the algorithm does not necessarily correspond to the actual results of each trial of the algorithm, as well as the effects of decoherence with respect to error.
