For example, if ``layer_pair_depths`` contains six depths and ``num_randomizations`` is set to ``32``, the noise learning stage executes a total of ``6 * 9`` unique circuits per layer, each one with ``32`` randomizations (at :attr:`~shots_per_randomization` each). The number ``9`` above is the number of unique circuits that need to be implemented to learn the noise for all the two-qubit subsystem in the given layer by performing local measurements. Indeed, learning the noise for a single one of these subsystems requires measuring all the ``16`` two-qubit Paulis on that subsystem. Taking advantage of commutation relations to measure more than one of these Paulis (for example, ``XI``, ``IX``, and ``XX``) with a single circuit, it is possible to measure all these ``16`` Paulis by implementing only ``9`` circuits. Parallelizing these measurement tasks in the optimal way allows then measuring the ``16`` Paulis for all of the layer's two-qubit subsystems with only ``9`` circuits. More details in Ref. [1].
