    • The quantum-state tomography shown here can be implemented in different ways. Typically, only three high-precision measurements are needed for a single qubit. For multiple qubit-state tomography, of course, such a simplified scheme becomes mandatory. However, the full two-dimensional scan allows us to resolve the rotation angle with high precision, determine the visibility shown in Fig. 3C, easily avoid any calibration errors in the microwave frequency, and fully test for proper state rotations.
