Systems and techniques that facilitate qubit pulse calibration via canary parameter monitoring are provided. In various embodiments, a system can comprise a measurement component that can measure a canary parameter associated with a qubit control channel. In various embodiments, the system can further comprise a scaling component that can modify a plurality of parameters associated with the qubit control channel via a scaling factor. In various cases, the scaling factor can be based on the canary parameter. In various embodiments, the canary parameter can be a rotation error of a qubit driven by a microwave pulse transmitted along the qubit control channel. In various embodiments, the plurality of parameters can be amplitudes of a plurality of microwave pulses transmitted along the qubit control channel. In various embodiments, the plurality of parameters can be phases of a plurality of microwave pulses transmitted along the qubit control channel.
