Abstract: A functional gate-based quantum computer requires a very high level of precision to implement quantum gates. As current devices get bigger, it proves difficult to maintain this level of control. To overcome such limitations, the most prominent solution is provided by the theory of quantum fault tolerance. However, it has still remained an open question how much a practical application can profit from the theory. For this reason, we extensively test a recent protocol to demonstrate quantum fault tolerance on real-time simulations and on the IBM Q Experience. We find that the fault-tolerant scheme provides a systematic way to improve the results when inherent control and measurement errors are dominant. However, the scheme fails to satisfy the criterion for fault tolerance when decoherence effects become important.
