From: Experimental test of the relation between coherence and path information
The Bagan’s equality defined by the duality relation between coherence and path information. Sum of C square and P square of all generated states are listed and compared with the theoretical bound 0.25, where the parts with grey (pink) background are the results obtained with state tomography (optimised positive operator valued measure (POVM)). All the states obey this new duality relation and Bagan’s equality is well satisfied with acceptable errors
