A binary-search Bayesian estimator running on an FPGA calibrates a transmon qubit's frequency in a handful of single-shot measurements, improving coherence and gate fidelity.
For instance, if in the previous measurement the qubit was in the ground state si−1 = 0 and now it is in the excited state ( si = 1) then mi = +1
