Alternatives to process tomography and gate set tomography
I need to characterize an unknown 2-qubit operation. As I understand it, quantum process tomography (QPT) can do this, but will not account for state preparation and measurement (SPAM) errors. On the other hand, gate set tomography provides a full…

What do the gauge freedom and fix the gauge mean in gate set tomography?
Recently, I have seen many papers involving the concept of gauge freedom, but I have not yet got a good understanding of it.
For example, in the paper: https://quantum-journal.org/papers/q-2021-10-05-557/pdf/, Why Gate set models may have gauge…
