Accred rework #578

Closed sethmerkel closed 3 years ago

sethmerkel commented 3 years ago

Summary

An update to the accreditation protocol to incorporate the fitting routines from [1].

Details and comments

We have updated the accreditation fitter class to use the protocol from [1] in addition to the routine from [2]. The new fitting protocol loses some of the originals ability to correct for non-Markovianity on the timescale of an experiment in order to give an improved bound.

Most of the changes have been made to the fitter class, which was reworked to allow for two protocols, however changes have also been made to the QOTP in order in order to increase flexibility and to remove some deprecated function calls.
