Error gen projection basis must be Basis object #455

Open pcwysoc opened 2 weeks ago

Describe the bug Error generator projections require a Basis object and do not work with a basis name, i.e. 'pp'. This is not the expect behavior as listed in the documentation. The issue appears to be with how the errorgen_and_projections function in reportables.py handles basis information.

Environment (please complete the following information):

pyGSTi version feature-qiskit-mcm
python version 3.10
OS Ventura 13.6.7

This should be an easy fix, mx_basis needs a Basis.cast(mx_basis) prior accessing .name or something similar. We'll probs need to infer the dimension from the incoming errgen matrix.
