fit_two_freq and fit_photon_ramsey should return a generic fit, for consistency with other fit functions.

MLTomo requires the observables to be POVMS. If we're hacking in Hermeticity,, we should try to do the same for other requirements in MLTomo: positive-semidefinite and trace >1.

There are currently no checks in Qlab.jl for these conditions or ways to pick the closest CPTP obs.

We need to update the code base so it works in newer versions of Julia.

Hi,

I find that the savitzkyGolay() filter is not working properly on the boundary points.

Take this simple example, with first order polynomial and window size 5:

x=[1,2,3,4,5,6,7,8,9,10]
savitzkyGolay(x,5,1)

where the correct result should be x, but the corresponding function in Julia returns:

1.6
2.2
3.0
4.0
5.0
6.0
7.0
8.0
8.8
9.4

Hope there's a quick fix! Thanks!

For reasons I haven't yet figured out the Julia and MATLAB resonator fit routines give different answers, especially for resonators at low power. I'd use the Julia code with caution for now.

See https://github.com/BBN-Q/Qlab.jl/blob/master/src/tomography.jl and https://github.com/BBN-Q/Qlab/blob/develop/analysis/cQED_dataAnalysis/analyzeProcessTomo.m

Investigating...

The plot option in single_shot_fidelities_2D requires one or both of PyPlot.jl or LaTeXStrings.jl.

Update Project.toml file to new format.
