Quantum computing is an alternative type of computation that has the potential of outperforming classical computation in some specific problems. While shown to be theoretically possible, currently there are several technical challenges that prevent the construction of a quantum computer big enough to be useful. Among these, there is the fact that qubits, the fundamental elements of quantum computation, are highly susceptible to external sources of faults, such as ionizing radiation. These faults are also called transient faults, due to their temporary nature. The work done in this thesis aims to better understand how transient faults propagate and corrupt the execution of quantum circuits, through the simulation of faults impacting the quantum circuits.
