Comments on "Efficient classical simulation of the Deutsch–Jozsa and Simon's algorithms".

A recent paper (Quantum Info. Process 16.9, 2017) proposes a classical framework named Quantum Simulation Logic (QSL) capable of an efficient classical simulation of Deutsch–Jozsa and Simon algorithms. In this comment, we show instances of the Deutsch–Jozsa (DJ) and the Simon quantum algorithms that generate incorrect results with the QSL version, contradicting the proposal and the main results of the original paper.
