StarkRamsey

Can we implement a Stark shift Ramsey like https://qiskit-community.github.io/qiskit-experiments/stable/0.7/manuals/characterization/stark_experiment.html

And then we can have also a T2 vs Startk_shifted frequency routine (or just use thee T2* from the previous one). This is very useful to characterize TLS spectrum for fixed frequency qubits.

We can certainly do that!

Note

Resonator Stark shift: We could even consider if it's worth trying to Stark-shift through the resonator.

The advantage should be a larger coupling, and thus a larger dynamical range for the qubit frequency. The downside is instead related to the depletion time: we mostly want to read a depleted resonator, but if we populate it on purpose to Stark-shift the qubit we want it not to be depleted during the experiment. Thus, we should wait for depletion after the drive sequence - but we can not wait too much because of the coherence (which unfortunately it should scale together with the depletion time...)
