The previous part demonstrates the potential of decision diagrams for noise-aware quantum circuit simulation. These simulators that have been proposed, implemented, evaluated, and published as open-source allow users to examine how their quantum applications would behave when executed on a real quantum computer. A class of quantum algorithms for which such a noise-aware quantum circuit simulation is essential is quantum error correction schemes. These schemes correct errors that occur in real quantum hardware, and as such are believed to be essential in creating an error-prone environment for executing large quantum applications [88].
