  We use quantum process tomography to characterize a full universal set of
all-microwave gates on two superconducting single-frequency single-junction
transmon qubits. All extracted gate fidelities, including those for Clifford
group generators, single-qubit pi/4 and pi/8 rotations, and a two-qubit
controlled-NOT, exceed 95% (98%), without (with) accounting for state
preparation and measurement errors. Furthermore, we introduce a process map
representation in the Pauli basis which is visually efficient and informative.
This high-fidelity gate set serves as another critical building block towards
scalable architectures of superconducting qubits for error correction schemes.
