pygsti.tools.optools.effect_label_to_povm

effect_label_to_povm(povm_and_effect_lbl)

Extract the POVM label from a “simplified” effect label.

Simplified effect labels are not themselves so simple. They combine POVM and effect labels so that accessing any given effect vector is simpler.

If povm_and_effect_lbl is None then “NONE” is returned.

Parameters:

povm_and_effect_lbl (Label) – Simplified effect vector.

Return type:

str
