      abstract     = {In the model of gate-based quantum computation, the qubits
                      are controlled by a sequence of quantum gates. In
                      superconducting qubit systems, these gates can be
                      implemented by voltage pulses. The success of implementing a
                      particular gate can be expressed by various metrics such as
                      the average gate fidelity, the diamond distance, and the
                      unitarity. We analyze these metrics of gate pulses for a
                      system of two superconducting transmon qubits coupled by a
                      resonator, a system inspired by the architecture of the IBM
                      Quantum Experience. The metrics are obtained by numerical
                      solution of the time-dependent Schrödinger equation of the
                      transmon system. We find that the metrics reflect systematic
                      errors that are most pronounced for echoed cross-resonance
                      gates, but that none of the studied metrics can reliably
                      predict the performance of a gate when used repeatedly in a
                      quantum algorithm.},
