I'm working on the readout error mitigation on a set of results obtained from different quantum circuits. The method I want to apply is to generate the confusion matrix for each quantum circuit (as the noise might change with time), and then use a filter to reduce readout errors. However, this might cost a long time since for each circuit in my experiment, I need to generate a set of calibration circuits to obtain the confusion matrix. I wonder is there a way I can import real-time error data of quantum devices in qiskit, so I don't need to repeat the standard error mitigation procedure many times?
Update: I found one plausible option would be using qiskit runtime program:
# Set the "circuit-runner" program parameters params = provider.runtime.program(program_id="circuit-runner").parameters() params.circuits = qc params.measurement_error_mitigation = True
Where I could also specify the physical qubit on the quantum device that I want to use. I don't know if this will automatically mitigate the readout error for that specific physical qubit(s). Also, if I have 100 quantum circuits with 1 qubit, should I consider running them separately (since the error rate might change), or submitting them all at once? Thanks!
