Readout Assignment Fidelity Accuracy

[aorgazf]

The current implementation of single shot classification does not distinguish between state e and any higher states. This results in an inaccurate evaluation of the readout fidelity. When used to optimise the amplitude of the readout pulse, it then favours high powers that separate the clouds but that excite higher levels. We need a routine that can accurately distinguish at least g, e, and f and calculate readout fidelities more accurately.

As an example, this is the classification obtained after updating the readout amplitude with the best amplitude generated by the readout optimization routine.
