Calibrating magnetic flux control in superconducting circuits by compensating distortions on timescales from nanoseconds up to tens of microseconds
Fast tuning of the transition frequency of superconducting qubits using magnetic flux is essential, for example, for realizing high-fidelity two-qubit gates with low leakage or for reducing errors in ...

Also make sure that there are no bias-tees in your circuit that have a non-linearity, observable as a power-dependence of the response function, which may hamper your efforts.

A lot more research and development needs to be done to have large scale fault-tolerant quantum computers to become a reality. Small quantum computers, with all the functionality exist though to try out concepts and develop algorithms also for quantum error correction.
