Qiskit Mitigation

Qiskit Mitigation is a package for handling noise in quantum computations. It contains a set of techniques that can be used to build advanced or customized error mitigation pipelines directly with samplomatic. Specifically, it contains:

1. Implementations of PEC, TREX, PEA, and gate folding ZNE
2. Functionality for computing a postselected noise channel, from circuit symmetries or spacetime checks, to be used with PEC to reduce sampling overhead
3. Postselection using non-Markovian error checks to filter corrupted samples out of measured data
4. Support for expectation value calculation with advanced error mitigation
