abstract = {We extensively test a recent protocol to demonstrate
quantum fault tolerance on three systems: (1) a real-time
simulation of five spin qubits coupled to an environment
with two-level defects, (2) a real-time simulation of
transmon quantum computers, and (3) the 16-qubit processor
of the IBM Q Experience. In the simulations, the dynamics of
the full system is obtained by numerically solving the
time-dependent Schrödinger equation. We find that the
fault-tolerant scheme provides a systematic way to improve
the results when the errors are dominated by the inherent
control and measurement errors present in transmon systems.
However, the scheme fails to satisfy the criterion for fault
tolerance when decoherence effects are dominant.},
